-	is integral by trying to convert back to floating point and seeing
-	if the value matches.  This is more robust than trying to test
-	whether the floating-point value is representable as an integer.

-
-	* awkgram.y (read_one_line): New function, mainly for debugging,
-	that reads one line of data at a time to pass back as a buffer.
-	Emulates the variable-length record filesystem of VMS, where
-	we first saw the problem fixed here.
-	(get_src_buf): New variable `readfunc' which is a pointer to a
-	function implementing the `read' system call interface. Based on
-	an environment variable, use `read_one_line' instead of `read'
-	for testing.   Make the test for expanding the buffer smarter,
-	so that it doesn't grow unnecessarily.
-
-	Thanks to Galen Tackett (tackett_galen@bah.com) for reporting
-	the problem and to Anders Wallin and Pat Rankin for help

-
-Wed Jul  6 16:44:58 2005  Jim Meyering  <jim@meyering.net>
-
-	* main.c (init_fds): If any of the STDIN_FILENO, STDOUT_FILENO,
-	STDERR_FILENO are initially closed, reopen them with permissions
-	contrary to common usage so that any reasonable attempt to use
-	them will evoke the same sort of error as reading or writing to

-
-	* io.c (iop_alloc): Let an input processor hook installed via
-	`register_open_hooks' open its own fd in case gawk does not know
-	how to open it.
-	(iop_open): Call `os_close_on_exec' after `iop_alloc'.
-	ADR: If `iop_alloc' returns NULL but the fd is valid, close

-
-	* dfa.c (lex): Fix bug #9519: "echo do^re | grep do^re" was

-
-Fri Apr 29 00:28:46 2005  Arnold D. Robbins    <arnold@skeeve.com>
-
-	* configure.ac: Jump through an amazingly convoluted hoop to get

-	work though.
-
-Thu Apr 28 23:40:02 2005  Stepan Kasal  <kasal@ucw.cz>
-
-	* configure.ac (PRINTF_HAS_F_FORMAT): Some cosmetic changes.

-
-	* field.c (set_FIELDWIDTHS): Tighten up the code to accept FIELDWIDTHS
-	values in [1..INT_MAX], e.g., detect overflow and invalid strings,

-Thu Apr 28 23:05:33 2005  Stepan Kasal  <kasal@ucw.cz>
-
-	* dfa.c (parse_bracket_exp_mb): Shorten one part of the code, to get

-
-Thu Apr 28 23:00:58 2005  Pat Rankin    <rankin@pactechdata.com>
-
-	* builtin.c (format_tree) [#if VAXCRTL]:  For floating point
-	formatting, reject zero_flag if using old VAXCRTL run-time
-	library to avoid getting erroneous results which appear as if
-	numerically incorrect (due to an embedded space in some cases,
-	extra trailing zeroes in others) rather than just misformatted.
-	`hsprint' test still fails, but not as badly.
-
-Thu Apr 28 19:12:03 2005  Arnold D. Robbins    <arnold@skeeve.com>
-
-	* re.c (reflags2str): Add three new RE_ flags from current regex.h

-
-	* builtin.c (format_tree): Save 2 spare bytes instead of one. Suggested
-	by Stepan Kasal.
-
-Thu Apr 28 18:16:09 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>
-
-	* awk.h (IOBUF): Add new fields `opaque', `get_record', and
-	*close_func', to support insertion of an alternate input processor.
-	This is used by the XML extension.
-	(register_deferred_variable, register_open_hook, update_ERRNO_saved):
-	Declare new functions.
-	(load_environ, load_procinfo): Remove declarations -- these functions
-	are no longer global, since we use register_deferred_variable instead.
-	* awkgram.y (register_deferred_variable): New function to allow
-	calling code to register special variable names that trigger a callback
-	upon the first reference.  This is now used to implement ENVIRON
-	and PROCINFO.
-	(variable): Search the list of deferred variables instead of hardcoded
-	tests for ENVIRON and PROCINFO.
-	* eval.c (set_BINMODE): Fix spelling of "arbitrary" in warning message.
-	(update_ERRNO_saved): New function that allows the caller to specify
-	the errno value instead of using the current value.
-	(update_ERRNO): Implement by calling update_ERRNO_saved(errno).
-	* io.c (iop_close): Call `iop->close_func' if non-NULL.
-	(close_redir): Should save `errno' value, otherwise `lintwarn' messages
-	might update it.  Then use `update_ERRNO_saved' to set ERRNO.
-	(do_getline): Call `update_ERRNO_saved' to set ERRNO based on the
-	error code returned by the redirect function (instead of the current
-	value of errno).  Similarly, use `update_ERRNO_saved' to set ERRNO
-	based on the value returned by `get_a_record'.  But add a special
-	check to avoid updating ERRNO if `get_a_record' returns an error
-	code value of -1 (this is used by the XML extension which already
-	sets ERRNO before returning).
-	(register_open_hook): New function to register a function to be
-	called whenever a new data file is opened.  This can be used to
-	install a special input processor (as in the XML extension).
-	(iop_alloc): Call registered open hook.
-	(get_a_record): If a `get_record' method has been set, call that instead.
-	* main.c (init_vars): Use `register_deferred_variable' to implement
-	ENVIRON and PROCINFO.
-	(load_environ, load_procinfo): Now static instead of global.
-	* doc/gawk.texi: Document new internal functions `update_ERRNO_saved',
-	`register_deferred_variable', and `register_open_hook'.

-	(tmp_integer): Don't do bit shifting if have long doubles.

-
-	* regex_internal.c (re_dfa_add_node): Remove variable `type'

-
-	Reinstate patch of 18 Nov 2001, for VMS, at least:
-
-	* random.c (srandomdev): ifdef-out.  Lots of compile time
-	  problems on multiple platforms, and gawk doesn't even

-
-	Fix obscure issue. ^ in RS should only match at the very
-	beginning of the input.  Essentially, the file is one long
-	string.  To do this, use the `not_bol' flag in the `struct
-	pattern_buffer'.  Thanks to Stepan Kasal for pointing out the
-	problem and to Andreas Schwab for pointing out the mechanism
-	for a solution.
-
-	* awk.h (RE_NEED_START, RE_NO_BOL): New flags for `research'.
-	(IOP_AT_START): New flag for IOBUF.
-	(research): Last parameter is now `flags'.
-	* builtin.c (do_match, sub_common): Change calls to `research'.
-	* eval.c (interpret, match_op): Same.
-	* field.c (re_parse_field): Same.
-	* io.c (spec_setup): Add IOP_AT_START flag.
-	(iop_alloc): Same.

-	add RE_NO_BOL to flags value in call to `research'.
-	(get_a_record): Clear IOP_AT_START upon return from `*matchrec'.
-	(iopflags2str): Add IOP_AT_START to table.  Also IOP_CLOSED,
-	which was missing. (Ooops.)
-	* re.c (research): Last paramater is now flags.  Modify logic to
-	handle RE_NO_BOL case by setting the right bit initially. Clean
-	up control flow so that it's cleared before returning.  If RE_NO_BOL,
-	don't bother with the dfa matcher, as it doesn't have an analogous
-	capability.

-Wed Dec 22 12:33:48 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	For --exec, don't allow x=y assignments where filenames would be.
-	Do allow -v.  This is because we assume --exec is used mainly for
-	CGI stuff and we don't want var assigns to affect the code.
-
-	Suggested by Stepan Kasal; motivated by reading about web security.
-
-	* main.c (disallow_var_assigns): New variable.
-	(main): Set the var for --exec.
-	(arg_assign): Check it appropriately.
-
-Sun Dec 19 17:27:09 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* builtin.c (do_gensub): Make `global' flag smarter, such that
-	a string numeric constant (e.g., "3") acts like a numeric
-	constant.
-	* node.c (r_force_number): Not really related: Only set NUMCUR
-	if we actually convert some digits.
-
-Sun Dec 19 16:08:50 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* dfa.h, dfa.c: Synchronize with what's happening in GNU grep

-	* hard-locale.h: New file, extracted from old dfa.c.
-	* Makefile.am (base_sources): Add hard-locale.h.
-
-Sun Dec 19 11:13:45 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* io.c (socketopen): Change type of `readle' and `namelen'
-	variables to size_t.  For QNX, but a good idea anyway. Thanks
-	to `Anthony' (rz1a@mail.ru).
-
-Mon Dec  6 11:11:22 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	Undid change of Mar 9 2004, to add gofast patch.  It gets things
-	wrong for gawk.  This removes the bandaid of ifdef-ing out the
-	main check.  Eventually this'll all get straightened out in the
-	GNU grep code.
-
-	* dfa.c (buf_offset): Removed.
-	(SKIP_REMAINS_MB_IF_INITIAL_STATE): Removed use of buf_offset, do
-	free `mblen_buf', `inputwcs'.
-	(match_anychar, match_mb_charset, transit_state_consume_1char,
-	transit_state): Remove use of buf_offset in mblen_buf.
-	(dfaexec): Use `free' and `malloc', not `realloc'.

-Mon Dec  6 10:55:37 2004   Fumitoshi UKAI       <ukai@debian.or.jp>
-
-	Forwarded from james@nocrew.org, the Debian contact.
-
-	* dfa.c (parse_bracket_exp_mb): 
-	1. Build range correctly when IGNORECASE for [a-a] to also get 'A'.
-	2. For [:lower:] and [:upper:], if ignoring case, set type string
-	   to "alpha".  This parallels code in the regex routines.
-	3. Reset wc1 to EOF when parsing bracket expressions.
-
-Mon Nov 29 18:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* io.c (redirect): When allocating a new struct redirect, set
-	rp->pid to -1, not 0, so that code checking for EOF on an
-	input pipe works correctly.
-
-Thu Nov 25 14:22:41 2004  Stepan Kasal  <kasal@ucw.cz>
-
-	* Makefile.am (MAINTAINERCLEANFILES): Add.

-	regexes, /.../i and /.../s.  Not that it'll help anyone.
-
-Wed Oct 27 14:25:18 2004  Stepan Kasal  <kasal@ucw.cz>
-
-	* builtin.c (do_tolower, do_toupper): Fix the wide char handling,
-	  especially when the lowercased char doesn't ocuppy the same
-	  number of bytes as its uppercase equivalent.  Make use of ...
-	(wide_tolower_toupper): ... this new static function.
-
-Mon Oct 25 11:51:14 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* builtin.c (bchunk, bchunk_one, cksize): Change type of `olen'
-	to size_t from long.  It is the 21st century now, after all...
-	Thanks to Stepan Kasal.
-
-Mon Oct 11 10:49:09 2004   Arnold D. Robbins    <arnold@skeeve.com>

-
-	* node.c (isnondecimal): Made smarter, so that 0xEE does
-	register as non-decimal. Added parameter to indicate use of
-	locale's decimal point and changed declaration and callers.
-
-Tue Sep 28 18:38:17 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* node.c (isnondecimal): New function, now smarter.
-	* awk.h (isnondecimal): Changed from macro to function.
-
-Wed Sep 22 11:24:46 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* dfa.c (dfamust): At end, check results of `malloc'.

-	for grep.
-
-Mon Sep 20 13:18:18 2004   Arnold D. Robbins    <arnold@skeeve.com>

-
-	* main.c (optab): New long option, --exec.
-	(main): Catch it.  Like -f but end option processing.
-	(usage): Add it to the usage message.
-
-	Thanks to John DuBois and Don Stokes for their input.
-

-
-	* main.c (main): Force LC_NUMERIC locale to "C" before parsing
-	the program, since a variable assignment with -v can leave the 
-	locale set incorrectly.
-
-	Thanks to Sirix <sirix@poczta.onet.pl> for reporting the problem.
-
-Wed Aug 25 18:55:30 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* main.c (UPDATE_YEAR): New constant at top of file, where we
-	won't miss it.
-	(copyleft): Use it.
-
-Sun Aug 22 17:26:39 2004   Stepan Kasal  <kasal@ucw.cz>
-
-	Define gawk_mb_cur_max even if there is no mbs support, as
-	``const int'' and assign 1 to it.
-	This fixes a bug in re.c where #ifdef MBS_SUPPORT was missing.
-
-	* awk.h (gawk_mb_cur_max): Declare.
-	* main.c (gawk_mb_cur_max): Define.
-	* awkgram.y (nextc_is_1stbyte): Without mbs support, define to 1.

-Sun Aug 15 22:08:04 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	Import current FreeBSD random.c.  Make it work for gawk.
-	Needed for cases where long is more than 32 bits.
-
-	* random.c: Imported from FreeBSD. Header includes tweaked.
-	* random.h: Typdef gawk_uint32_t appropriately and #define uint32_t
-	  to it.
-	* configure.ac: Add calls to AC_CHECK_SIZEOF for unsigned int
-	and unsigned long.
-
-	Started with
-	http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/stdlib/random.c
-	Thanks to Andreas Schwab <schwab@suse.de> for the pointer.
-
-Thu Aug 12 13:09:53 2004   Arnold D. Robbins    <arnold@skeeve.com>
-

-
-Mon Aug  2 12:17:40 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* configure.ac: Fix the hack. Do the sed on `Makefile',
-	not `Makefile.in'.  Sigh.
-
-Sun Aug  1 14:48:30 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* configure.ac: MAJOR HACK: At end, remove version.c from Makefile.in
-	variable `CONFIG_CLEAN_FILES' so that `make distclean' doesn't
-	remove version.c.
-
-Mon Jul 19 17:07:27 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* config.guess, config.sub: Updated from Savannah CVS.

-
-	* re.c (make_regexp): Bracket code using `gawk_mb_cur_max'

-
-Thu Jul 15 12:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>
-
-	* dfa.c (parse_bracket_exp_mb):  If doing case folding,
-	include the other case for regular characters inside [...].
-
-	* re.c (make_regexp): Smarten up handling of IGNORECASE,
-	particularly for multibyte character sets. Sigh.
-
-Wed Jul 14 16:25:23 2004  John Haque  <mary1john8@earthlink.net>
-
-	* eval.c (interpret): For `Node_K_return', use `copynode'
-	and not `dupnode' for non-PERM, non-TEMP values.
-	(func_call): Don't add TEMP flag to returned value.
-
-	These two fix a problem uncovered by the July 8 change in
-	`assoc_lookup'.

-	  pointer.  The bug was triggered by the following code:
-
-		gawk 'BEGIN{print "date" |& getline}'
-
-	No test case created, beacuse of the following:
-	Correct interpretation involves executing "1" or "0" -- as the user
-	may have defined this, we would have to override this in the test
-	script.  It's not worth the hassle.
-
-Thu Jul  8 12:59:49 2004  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* awk.h (load_casetable): Name changed from `load_ignorecase'.

-
-	* awkgram.y (get_src_buf): Fix off-by-one error to avoid "does not end
-	in newline" messages.
-	* array.c (assoc_lookup): Small performance hack: for TEMP subs nodes,
-	use its string memory for ahname.
-	* ext.c (get_actual_argument): Minor code cleanup.
-	* builtin.c (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl):
-	fixed to issue "non-numeric argument" lint warnings before using
-	`force_number'.
-
-Mon Jun 21 16:53:35 2004  Arnold D. Robbins  <arnold@skeeve.com>
-

-	name of new function, and that it's not a redefinition.
-	(get_argument): Check that requested arg is within range of actual
-	number of parameters.  Also clean up logic for Node_var_new,
-	Node_var_array, Node_array_ref.
-	(get_actual_argument): New function.
-	* profile.c (pp_builtin): Better handling of dynamic extension function.
-
-Sun Jun 13 14:32:22 2004  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* io.c (redirect): Conditionalize checking for process recovery
-	on `#ifdef PIPES_SIMULATED'.  Needed for MS-DOS and VMS.
-	* builtin.c (tmp_integer): Change bracketing of magic test to
-	`#ifdef HAVE_UINTMAX_T' which is more general and more correct.
-
-Wed Jun  9 21:36:01 2004  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* re.c (make_regexp): Add dfa matching into IGNORECASE handling.

-
-Tue Jun  8 13:54:28 2004  John E. Haque      <mary1john8@earthlink.net>
-
-	* awkgram.y (statement:LEX_FOR): Fix bug in loop to `delete a'
-	optimization.
-	* io.c (format_tree): Check for out of range values for
-	positional specifiers.
-
-Mon Jun  7 17:02:48 2004  Arnold D. Robbins  <arnold@skeeve.com>

-
-Sun Jun  6 18:35:17 2004  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* io.c (get_a_record): Restore use of `memmove' instead of
-	memcpy. Otherwise some tests break on some systems. We think.

-
-Thu Jun  3 14:06:06 2004  Arnold D. Robbins  <arnold@skeeve.com>
-

-
-	Unrelated: Avoid warning:
-
-	* main.c (main): Cast calls to `bindtextdomain' and `textdomain' to
-	void.  Avoids diagnostic with `configure --disable-nls'.
-	* dfa.c (check_matching_with_multibyte_ops): Remove unneeded nested
-	#ifdef, per Scott Deifik (scottd@amgen.com).  Also fix some spelling
-	errors in comments.
-
-Tue Jun  1 18:26:45 2004  Paul Eggert  <eggert@twinsun.com>
-
-	Fix a bug reported by Mike Romaniw <msr@micromonumental.com>
-	to bug-gnu-utils on 2003-09-27: compl(compl(0xf0f)) returned 0xfff
-	on hosts with 64-bit uintmax_t and 64-bit IEEE-764 double, due to
-	rounding errors.
-
-	* doc/gawk.texi (Bitwise Functions): Leading nonzero bits are
-	removed in order to fit the result into a C 'double' without rounding
-	error.
-	* builtin.c: Include <float.h> if available.
-	(FLT_RADIX, FLT_MANT_DIG, DBL_MANT_DIG): Define if not already defined.

-
-	* eval.c (make_scalar): Comment clarification.
-
-	* array.c (get_actual): Remove the condition ``canfatal''

-
-	* awkgram.y (variable): Make one longer message, to help translators.
-

-
-Wed Mar  3 17:10:16 2004  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* io.c (close_one): Don't close stdout or stderr; can happen if

-
-	* awkgram.y (rule): Use `msg' not `warning' for `must have an
-	an action part' message.  `warning' is wrong, since it's a real error.

-
-	* main.c, eval.c, builtin.c: Change test for `#ifdef HAVE_LOCALE_H'
-	to `#if ENABLE_NLS && defined(HAVE_LOCALE_H)' so that builds with
-	`configure --disable-nls' will actually work on non-glibc systems.

-	Node_array_ref changes to a scalar variable.
-	(tree_eval, get_lhs): Call it.
-	(tree_eval): From now on, tree_eval(NULL) doesn't work;
-	it reports an internal error.

-	always the return value, never NULL.
-
-	* Makefile.am (install-exec-hook, uninstall-links): Make use of

-	(re_search_internal): Pass new parameter to check_matching.

-
-	* re.c (research): Change last param to re_search to pass

-
-	* builtin.c (sub_common): Add comment and support for 2001 POSIX

-
-	* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.13.1.

-
-	* dfa.c, dfa.h: Updated manually with most of the changes in
-	grep 2.5.1.  That version lost the ability to match newlines

-
-2004-01-12  Paolo Bonzini  <bonzini@gnu.org>
-

-	just makes the code less clear.
-	(parse_bracket_exp): Use NON_MATCH variable in
-	addition to "mbcset->non_match", not as an
-	alternative.

-	NON_MATCH, use it instead of declaring a variable. 
-	(parse_bracket_exp) [!_LIBC]: Pass NULL for MBCSET

-
-Wed Sep 24 17:32:31 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	Speed up `avoid_dfa' kludge, at least a little:
-
-	* awk.h (struct Regexp): Add `has_anchor' member.  Make it and
-	`dfa' member shorts; keeps space the same.
-	* re.c (make_regexp): Set `has_anchor' member correctly.

-
-Sun Sep 21 18:34:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

-	as used in `match_op'.  Sigh.

-	testing of things with/without the dfa matcher.
-
-Mon Sep 15 18:36:38 2003  Arnold D. Robbins  <arnold@skeeve.com>
-

-
-	* io.c (useropen): Add `defined (HAVE_GETGROUPS)' as first test
-	in `#ifdef'.  Brings things in sync with same test in main.c and awk.h.
-

-
-	* dbug.h: New file.

-	* array.c, awkgram.y, builtin.c, eval.c, ext.c, field.c, io.c,
-	main.c, msg.c, node.c, profile.c, re.c: Converted to use
-	Fred Fish's `dbug' library.  By default compiled out, thus
-	not affecting speed.
-
-	For the nonce, the `dbug' library itself is not shipped with
-	gawk, since I expect no-one else but me to be using it.

-
-2003-07-06  Paul Eggert  <eggert@twinsun.com>
-
-	* builtin.c (do_substr): Issue better diagnostics when
-	d_substr and d_length are NaN, or when 0 < d_length < 1.

-	or are NaN.
-	(do_dcngettext): dcngettext wants an argument of type

-
-	* main.c (main): Make option letter 'D' fall through into default

-
-	* array.c (get_actual): Undo Stepan Kasal change of 2003-06-17.

-
-	* builtin.c (do_rand): Change calculation so that result

-
-Mon Jun 23 15:13:39 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* io.c (rs1scan): Per advice from Bruno Haible, it's safe
-	to skip the multibyte checking code if RS is '\n'. See

-	multibyte locales.
-
-2003-06-20  Stepan Kasal  <kasal@ucw.cz>
-
-	* eval.c (comp_func): If memcmp returns 0, we have to compare

-2003-06-10  Stepan Kasal  <kasal@ucw.cz>
-
-	* awkgram.y (release_all_vars): Do not try to release a value of
-	  Node_var_new; after get_lhs, use the lhs directly, do not try
-	  to do (*lhs)->var_value; the Node_var case doesn't need
-	  special treatment.
-	* builtin.c (do_match): `get_param' is successful iff it returns
-	  Node_var_array---if the variable was new, get_param has already
-	  changed the type.
-	* field.c (do_split): Likewise.
-
-Sun Jun 15 19:36:35 2003  Arnold D. Robbins  <arnold@skeeve.com>

-	(get_actual): Renamed 'prm' to `isparam'.
-	(array_vname): Add static msglen var; only realloc string if it grows.
-	Don't use `s += sprintf(...)'. No good on old systems where sprintf
-	returns char *.  Minor formatting cleanups.
-	(do_adump): Restored separate `a' and `r' variables; helps for debugging.
-
-	* awk.h (SCALAR, UNINITIALIZED): Removed entirely, renumbered other flags.
-	(get_array, get_param): New macros, calls get_actual.
-	(get_actual): Declaration changed from that of r_get_array.

-	needed comments.
-
-	* field.c (do_split): Use get_param and print our own message when
-	second parameter is not an array.
-
-Mon Jun  9 11:46:21 2003  Arnold D. Robbins  <arnold@skeeve.com>

-
-	* awk.h (Node_var_new): New node type for variables which can be
-	either scalar or array.  From now on, Node_var is always scalar.

-	(orig_var): Removed, orig_array is enough.
-	(SCALAR, UNINITIALIZED): Flags nuked.
-	(var_uninitialized): New macro to distinguish uninitialized vars;
-	used in several other macros.
-	* array.c (r_get_array, array_vname, do_adump): Adapt to the
-	above changes.
-	* awkgram.y, eval.c, field.c, main.c, node.c, profile.c: Ditto.
-
-Tue May 27 14:27:50 2003  Stepan Kasal  <kasal@math.cas.cz>
-
-	* array.c (r_get_array): New function, which goes all the way
-	through Node_param_list to actual Node_var_array; if it encounters
-	non scalar Node_var, it changes it to Node_var_array.
-	(in_array, do_delete, do_delete_loop, do_adump, assoc_sort_inplace):
-		Use get_array.
-	(assoc_lookup): The parameter must be a Node_var_array.

-Tue May 27 08:23:51 2003  Stepan Kasal  <kasal@math.cas.cz>
-
-	Changed node->vname meaning for type Node_array_ref and Node_gvar_ref.
-	It contains only the reference name; one has to (recursively) follow
-	node->prev_array to find out the call history for the array.
-
-	* array.c (array_vname): New function to print the array name.
-	(assoc_lookup, do_delete): Use array_vname.
-	* eval.c (interpret, r_tree_eval, r_get_lhs): Use array_vname.
-	(push_args, pop_fcall): Things have simplified.
-	* awk.h (array_vname): Declare.
-	(prev_array): Define.
-
-Sun Jun  8 11:25:36 2003  Stepan Kasal  <kasal@ucw.cz>
-
-	* awkgram.y (append_right): When using savetail, remember that it
-	is not necessarily the tail of the list---it's just a pointer to
-	the last chunk appended.
-
-Thu Jun  5 12:01:41 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* builtin.c (do_strtonum): Make `strtonum(13)' work.

-
-Tue Jun  3 12:40:50 2003  Arnold D. Robbins  <arnold@skeeve.com>

-	call `free_temp' on the result of `force_string' if it's equal to
-	switch_value. Thanks to John DuBois <spcecdt@armory.com>
-	for finding the problem.
-
-Sun Jun  1 13:08:22 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* builtin.c (format_tree): For %c, force precision to 1.
-
-Wed May 28 11:55:48 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* awkgram.y (isnoeffect, isassignable): Add Node_TEXTDOMAIN to
-	switches in both functions.
-
-Wed May 28 11:38:59 2003  Stepan Kasal  <kasal@math.cas.cz>
-
-	* awkgram.y (switch_body): Remove rule ``switch_body:/*empty/''
-	as ``switch_body:case_statements'' covers it---this disambiguation
-	fixes a reduce/reduce conflict.
-
-Sun May 25 16:23:43 2003  Corinna Vinschen  <vinschen@redhat.com>
-
-	* configure.ac: Remove linking against /usr/lib/automode.o.

-
-	* awk.h (get_lhs): For an initialized Node_var, you may return
-	the address of var_value pointer, no matter whether reference
-	bit was set or not.  We were silly slowing down most of the
-	assignements.
-
-	* (get_a_record): After grow_iop_buffer, move recm.rt_start even
-	if recm.len == 0.
-
-Mon May 19 16:55:59 2003  Arnold D. Robbins  <arnold@skeeve.com>
-

-
-	* io.c (rsnullscan, get_a_record): Boundary condition bug fixes.

-
-	* io.c (get_a_record): Only tweak RT's value in place if the current
-	RS scanner is the same as the last one. Bug report submitted by
-	John DuBois (<spcecdt@armory.com>).
-
-Fri May  2 14:39:48 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* io.c (get_a_record): Add logic at end to be smart about setting
-	RT.  Saves considerable time, esp for default case where RS = "\n".
-

-
-	* field.c (do_split): Add check and code for Node_gvar_ref.

-	(rs1get_a_record, rsnull_get_a_record, rsre_get_a_record): Removed.
-	(get_a_record): Rewritten, again. Now contains just buffer and
-	record code; searching code moved into these functions:
-	(rs1scan, rsnullscan, rsrescan): New functions to scan a buffer
-	for record contents and terminator. Fill in values in:
-	(struct recmatch): Holds found record and terminator.
-	(spec_setup): Set iop->dataend to indicate data is already in buffer.
-	(nextfile, inrec): Use new macros instead of flag and pointer tests.
-	(set_RS): Set scanning function instead of record function.
-
-	FWIW, it all passes `make test'.

-
-	* io.c (do_close): At end, if do_posix return 0. See comment in code.

-
-Sun Apr 13 16:02:10 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* main.c (main): Add call to `setlocale' for LC_NUMERIC after program is
-	parsed.
-	(arg_assign): Switch back to "C" locale for LC_NUMERIC for command
-	line assignments; this is per POSIX that period is decimal point for
-	program and command line assignments and the locale's separator
-	applies for input, output, and string to number conversion.
-
-2003-03-26  Paul Eggert  <eggert@twinsun.com>
-
-	* builtin.c [HAVE_INTTYPES_H]: Include <inttypes.h>.

-	(TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): New macros, taken from
-	coreutils and many other GNU utilities.
-	(format_tree): When formatting, use widest possible integers
-	rather than settling with 'long'.
-	(do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Likewise,
-	when doing bitwise operations.
-	* configure.in (jm_AC_TYPE_LONG_LONG, jm_AC_TYPE_UNSIGNED_LONG_LONG,
-	jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Add, since the mainline
-	code now needs this.
-	* doc/gawk.texi (Control Letters, Bitwise Functions): Document this.
-	* m4/intmax_t.m4: New file, taken from coreutils (but renamed to
-	avoid collision with our m4/inttypes.m4).
-	* m4/longlong.m4: New file, taken from coreutils.
-	* m4/uintmax_t.m4, m4/ulonglong.m4: Remove; superseded by the above
-	new m4 files.
-
-	* builtin.c (BITS_PER_BYTE): Remove; use CHAR_BIT instead, since
-	it's the standard name.
-	(do_lshift, do_rshift): Complain if the shift width is exactly equal
-	to the word size, too.
-
-Thu Mar 27 10:44:11 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
-	Enhance check for no data left in file to be only if file has
-	non-zero size.  Linux files such as /proc/filesystems stat as a
-	regular file of size 0, but actually have contents. Ugh.
-	Thanks to Martin Schlemmer <azarah@gentoo.org> for the bug report.
-
-Wed Mar 26 12:19:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

-	symbol table, but not a variable, array, or parameter, generate
-	a syntax error.
-	(isarray): New function, tests if a symbol can be an array.
-
-	* custom.h: Add check for HP/UX, needed for GCC.
-
-Mon Mar 17 09:21:09 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	Allow simultaneous manipulation of a global array directly
-	and when passed as a parameter.
-
-	* awk.h (Node_gvar_ref): New nodetype.
-	[orig_var]: New macro.
-	* array.c (do_delete_loop, do_delete): Add logic to handle
-	seeing Node_gvar_ref.
-	* eval.c (nodetypes): Add Node_gvar_ref.
-	(r_tree_eval, r_get_lhs): Add Node_gvar_ref case.
-
-Wed Mar 19 14:10:31 2003  Arnold D. Robbins  <arnold@skeeve.com>
-
-	This time for sure.

-
-	* Release 3.1.2: Release tar file made.
-
-Wed Mar 19 14:08:11 2003  Arnold D. Robbins  <arnold@skeeve.com>
-

-	* array.c (gst_hash_string, scramble): New functions.
-	(awk_hash): Renamed from hash.
-	(hash): Now a function pointer.

-	experimentation.
-
-Mon Oct 28 13:21:20 2002  Arnold D. Robbins   <arnold@skeeve.com>
-
-	Applied lots of patches from Stepan Kasal, tweaked as needed
-	for current code base.
-
-	* node.c (dupnode): When n->stref overfows, flag the node as PERM.
-	Same for n->ahname_ref.
-	(unref): Remove the check for n->stref == LONG_MAX and
-	n->ahname_ref == LONG_MAX.
-	* awk.h (make_string): The third argument to make_str_node changed
-	from FALSE to 0, it's not Boolean.
-	(free_temp): Evaluate the argument only once, so that we
-	can call free_temp(tree_eval(n)) for achieving side effects.
-	(load_environ, load_procinfo): Changed return type to NODE *.
-	* main.c (load_environ): The ENVIRON_node should be created with type
-	Node_var_array and lnode set to NULL.  Return pointer to the created node
-	and create an empty hash even on TANDEM.
-	(load_procinfo): Same mods for PROCINFO_node.
-	(init_args): ARGV_node should also have lnode set to NULL.
-	* eval.c (r_tree_eval): case Node_assign moved just above the other
-	assignment cases.
-	(op_assign): ++ and -- cases merged with += and -=, respectively.
-	(push_args): Evaluate all args, even in cases where more args are
-	supplied then required.
-	(interpret): In case Node_K_forarray, flag the variable
-	num_elems also as volatile, so that it survives longjmp() and
-	can be trusted when linting code.
-	(r_get_lhs): Case Node_param_list was unreachable (unless
-	something breaks really badly), remove it;
-	(r_tree_eval): Case Node_var_array removed from the last switch,
-	it was caught in the first switch above.
-	* profile.c (tree_eval): Again, case Node_var_array was caught above.
-	* awkgram.y (variable): Code simplified, making use of the above
-	changes.
-	* field.c (sc_parse_field): IGNORECASE only applies to regex based
-	field-splitting, so remove code that pays attention to it.
-	(do_split): Don't use parse_field if RS_is_null.
-	(set_FS): Beware of FS == "\\" even if RS_is_null.
-
-	Code changes to make things work better:
-	* field.c (set_FS): Don't use cmp_nodes() to compare old and new
-	value of FS, that uses IGNORECASE, which is a bad idea. Improve
-	logic for choosing sc_parse_field.  Ensure that when RS_is_null
-	but using a single character, that we do pay attention to
-	case when doing regex splitting.
-	* io.c (set_RS): Don't use cmp_nodes() to compare old and new
-	value of RS, that uses IGNORECASE, which is a bad idea.

-
-	* awk.h (STR, CUR): Changed to STRCUR and NUMCUR respectively,
-	to avoid conflict with STR on some System V systems.  Changed
-	in all source files.
-
-Thu Oct 24 16:14:34 2002  Arnold D. Robbins   <arnold@skeeve.com>

-Tue Oct 15 14:18:53 2002  Arnold D. Robbins   <arnold@skeeve.com>
-
-	* eval.c (set_IGNORECASE): Call set_RS() instead of
-	set_FS_if_not_FIELDWIDTHS().  The former calls the latter
-	for us, and also makes IGNORECASE affect RS like it's supposed to.
-	* field.c (FS_re_yes_case, FS_re_no_case): New variables.
-	(set_FS): Smarten up routine to not recompile FS_regexp if all
-	that's changed is IGNORECASE or if switching back to FS from
-	FIELDWIDTHS.  Significant speed-up for cases where IGNORECASE
-	is assigned to for every record.
-	* io.c (RS_re_yes_case, RS_re_no_case): New variables.
-	(set_RS): Similar changes as to set_FS().  In particular,
-	IGNORECASE changing now affects record splitting too.
-	* re.c (refree): Set rp->pat.tranaslate to NULL. It comes
-	from casetable and shouldn't be freed. (Strictly necessary
-	only for old regex, but a good idea anyway).
-	Also, call regfree(& rp->pat) instead of manually free()ing
-	things, since there's dynamically allocated stuff hiding in
-	the buffer. Avoids a memory leak.
-
-Mon Oct 14 12:02:39 2002  Arnold D. Robbins  <arnold@skeeve.com>
-

-	(ahname_len): New member, points into hash union.
-	(ahname_ref): New member, points into hash union.
-	* array.c: Replaces uses of ahname member with string and
-	length.  Set the reference count correctly to 1 on new nodes.
-	* eval.c (interpret): Case for Node_K_arrayfor.  dupnode() the
-	array indices, and set loop variable to new value made via
-	make_string().
-	* node.c (unref, dupnode): Node_ahash nodes are now also
-	reference counted, a la strings.  Similar code is used to
-	increment/decrement the counts, and/or copy nodes as
-	needed.
-
-	Unrelated:
-	* awk.h (forsub): Removed. Not used.
-
-Sun Oct 13 16:58:27 2002  Stepan Kasal  <kasal@math.cas.cz>

-	of the case.
-	* eval.c (interpret): Likewise.

-	* field.c (set_NF): ... to here.
-	* main.c (varinit): No need to call set_NF().
-	* awkgram.y (statements): Don't be so generous when concatenating
-	`statements' with a `statement'.

-	with a comment that it's internally the same as `delete array'.
-	* eval.c (Node_K_delete_loop): Increment the exec_count. Ooops.

-
-	* awkgram.y (statement): Moved delete, print, and expressions into
-	  new non-terminal `simple_stmt'.  Allow opt_simple_stmt in the

-
-Wed Nov 14 16:12:40 2001  Pat Rankin  <rankin@eql.caltech.edu>
-
-	* builtin.c (bchunk_one): Use `ofre < 1' instead of `ofre <= 0'

-
-	* io.c (redirect): When deciding to use the fdopen bug hack,
-	  use "__sun" rather than "solaris".  No compilers predefine
-	  "solaris", but both GCC and Sun C predefine "__sun".
-
-Thu Aug 30 15:17:12 2001  Arnold D. Robbins  <arnold@skeeve.com>
-
-	* main.c (copyleft): Use a printf %d for last year of update

-
-2001-08-13  Paul Eggert  <eggert@twinsun.com>
-
-	This patch fixes a bug that causes gawk to rewind standard
-	input incorrectly.  It also removes all instances of fseek,
-	from the gawk source proper, which should make gawk a bit
-	more portable.
-
-	(The original patch removed off_t & lseek too, but I need
-	that for something else. ADR.)
-
-	* posix/gawkmisc.c (optimal_bufsize):
-	Don't use lseek on the input, because that might change
-	its state.  Instead, just check whether it is a regular file.
-	This obviates the need to invoke isatty.
-	(Also, fix a spelling error in the first line of the source.)
-	* pc/gawkmisc.pc, unsupported/atari/gawkmisc.atr: Likewise.

-	  to protect against FS[1] = "x" kinds of things.  It'd be better

-	  effective.
-
-	Undid BECAMEARRAY changes of 25 June 2001 in favor of correct code:
-	* eval.c (pop_fcall): Change test and comment for freeing n->vname.
-	  (flags2str): Removed BECAMEARRAY entry.
-	* awk.h (BECAMEARRAY): Removed define.
-	* array.c (assoc_lookup): Removed setting of BECAMEARRAY flag.

-
-	* builtin.c (do_mktime): Allow the user to specify the
-	  tm_isdst member as an optional trailing integer, and to
-	  specify "out-of-range" members.  Check for overflow when

-	  profile.c (interpret): Ditto.
-	* main.c (pre_assign): Gross hack. malloc fresh copy of assign so can

-
-Sun Jan 28 16:16:02 2001  Arnold D. Robbins  <arnold@skeeve.com>

-
-	* awk.h (nextc): Remove declaration, don't need it here.

-
-	* regex.c (init_syntax_once): Move below definition of

-
-	* main.c (arg_assign): Add new arg, `initing' for icky special

-	  defines for my testing/debugging use.  Yes, hack alert.

-	* io.c (iop_alloc): Don't mmap files whose sizes don't fit in `int'.

-	* custom.h: Hacks for BeOS. Not documented in the manual right now.
-	* configure.in: Hacks for BeOS.  Check for HP-UX and define C_ALLOCA

-Tue Nov  3 16:24:35 1998  Arnold D. Robbins  <arnold@gnu.org>
-
-	* eval.c (r_get_lhs): Fix the cases for the special variables,
-	  don't unref their current value if it's the same as the internal
-	  copy; perhaps the current one is used in a concatenation or some
-	  other expression somewhere higher up in the call chain.  Ouch.
-	  See test/getnr2tm.awk.
-
-Sun Nov  1 15:24:52 1998  Arnold D. Robbins  <arnold@gnu.org>
-
-	* builtin.c (format_tree): Improve handling of zero-fill

-
-	* eval.c (r_tree_eval): Case for Node_concat. Get lengths
-	  separately, in case one expression has a side effect that
-	  that changes another. Ugly, but it keeps gawk from core
-	  dumping. See test/nasty.awk.
-
-Sun Oct 18 21:27:24 1998  Arnold D. Robbins  <arnold@gnu.org>
-
-	* awk.y (append_right): Bug fix, if `list' or `new' are NULL,
-	  return `list', so that things don't break too badly.

-
-Mon Mar 23 21:22:32 1998  Arnold D. Robbins  <arnold@gnu.org>
-
-	* eval.c (r_get_lhs): Make sure that values of type
-	  Node_param_list don't have the FUNC flag set. This means
-	  we don't allow the use of a function name as a variable or

-
-	* field.c (using_FIELDWIDTHS): New macro.
-	  (using_fieldwidths): Use new macro.
-	  (do_split): In case for FS_DFLT, also check that
-	  we're not using FIELDWIDTHS. Otherwise, split() would use
-	  FIELDWIDTHS, not current value of FS. Oops.
-
-Sun Nov 16 20:08:59 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* builtin.c (sub_common): Fix for count of matches in gsub

-
-Wed Oct 15 03:38:12 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* field.c (set_FS): Use `sc_parsefield' if the value of FS is not
-	  alphabetic OR if not ignoring case. Bug fix if IGNORECASE
-	  is true and FS happens to be '^'. Sheesh, talk about obscure.

-	  fields. Thanks to Alan J. Broder (ajb@dtmr.com).
-
-Sun Oct  5 11:56:52 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* configure.in: If ISC add -D_SYSV3 to CFLAGS, per email from

-
-Fri Sep 26 00:57:49 1997  Arnold D. Robbins  <arnold@gnu.org>
-

-
-	* field.c (rebuild_record): Set things up so that all fields point
-	  into the new record and release any changed fields without
-	  causing memory leaks.  Avoids problems when fields are extended

-
-Mon Sep 15 16:12:55 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* builtin.c (do_print): When testing for NUMBER, make sure
-	  it's not a string too. Thanks to Michael Brennan for

-
-Sun Sep 14 19:55:12 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* node.c (format_val): Always format values ourselves: avoids
-	  problems if OFMT is bizarre, like %s.
-
-Sun Sep 14 00:08:53 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* io.c (get_a_record): Replace all occurrences of the test
-	  `grRS == FALSE' with `RS_is_null' which makes ` RS = "\0" '
-	  actually work, is clearer code, and actually makes use of
-	  the `RS_is_null' variable!
-
-Sun Aug 17 07:15:12 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* field.c (set_FS): Change logic to always set parse_field, even

-
-Wed Aug  6 21:04:37 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* io.c (VMS et al gawk_popen): Use pclose, not fclose, if

-
-Thu Jul 17 20:05:59 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* builtin.c (do_print): When OFMT != CONVFMT, create a new
-	  temporary node with just the numeric value valid and format it,
-	  and use that for printing. Avoids memory corruption.
-
-Wed Jul 16 10:01:16 1997  Arnold D. Robbins  <arnold@gnu.org>
-
-	* regex.c: When SYNTAX_TABLE is defined, but not emacs, then
-	  CHAR_SET_SIZE is not defined, though used in regcomp.  It should
-	  be taken out of #ifdef SYNTAX_TABLE. Fix from bug group, from
-	  Akim Demaille, demaille@inf.enst.fr.
-	* awk.h (isnondecimal): Make test a little smarter.
-	* builtin.c (nondec2awknum): Add bailout for decimal numbers, e.g.

-
-Sun May 11 07:04:01 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-

-
-Wed May  7 15:09:25 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

-
-	* Makefile.in [COMPFLAGS]: Per suggestion from Karl Berry, put
-	  $(CFLAGS) last.
-
-Tue Apr  8 23:54:46 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* eval.c (interpret): For Node_K_break and Node_K_continue, if
-	  treating them like `next', also check the function call stack
-	  and pop it if necessary.
-
-Mon Apr  7 18:22:37 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

-
-	* io.c (iop_alloc, iop_close): Undo changes of Feb 11, apparently
-	  other cleanups in io.c made mmap stuff start working again.
-	  BAH! It's a mess, the test suite still fails. I'm leaving the
-	  mmap stuff undefined for now. It'll probably get ripped out in 3.1.
-
-Thu Mar 27 08:48:57 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* custom.h [_SEQUENT_]: Undef HAVE_MMAP.

-	  (init_fields, set_field, set_record) use the FIELD flag.
-	  (getfield): Use Null_field instead of private variable.
-	* io.c (wait_any): Comment out calls to pclose and iop_close,
-	  caused weird race conditions. See test/pipeio1.awk. Thanks

-
-Tue Mar 18 06:33:00 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.y (dup_parms): Robustified against parameter errors.
-
-Sun Mar 16 21:31:40 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
-	* acconfig.h [BITOPS]: New macro. If set, do octal & hex and bit ops.

-
-	* awk.h [IOP_NOFREE_OBJ]: New macro.
-	* io.c (iop_open, iop_alloc): Add new third parameter, which is
-	  either NULL, meaning allocate a new IOP, or the address of one
-	  already allocated.  Have a static one in the `nextfile'
-	  routine, and use the IOP_NOFREE_OBJ flag for it.  All of this
-	  keeps us from reading freed memory. The `swaplns' test fails
-	  otherwise.
-	  (iop_close): If IOP_NOFREE_OBJ is set, don't free the IOBUF.
-
-Wed Feb 26 06:21:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* eval.c (in_function, pop_fcall_stack, pop_fcall, push_args):
-	  New functions. These manage "frames" of awk function call arguments.
-	  The problem is that a `next' or a `nextfile' from a function
-	  leaks memory. These changes allow us to free up that memory.
-	  (interpret): for Node_K_next and Node_K_nextfile, check if in
-	  a function call and free all function call frames.
-
-Fri Feb 21 06:23:19 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

-
-Wed Feb 19 23:29:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* main.c (main): Add do_intervals to condition that causes
-	  resetup() to be called again. Makes the --re-interval option

-
-Fri Feb 14 09:47:31 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c [#include "awk.h"]: Undef HAVE_MMAP to just use the old code.
-	  Something is causing a file descriptor leak, and this is getting to
-	  be just too much hair. I reserve the right to rip out the mmap
-	  code entirely at a future date.
-
-Tue Feb 11 06:28:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (iop_alloc): For an mmap'ed file, close the file descriptor,

-	  of truncating our input file.
-	  (iop_close): Don't call close on mmap'ed file.
-
-Wed Feb  5 17:59:04 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-

-	  it handle the case of `delete array'.
-	* array.c (do_delete): Changed to handle case of `delete array',
-	  and made smarter if the array is actually an uninitialized
-	  parameter.
-
-Sun Jan 26 22:58:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* getopt.h, getopt.c, getopt1.c: Replaced with new versions from

-	* eval.c (nodetype2str): Not static, for debugging.
-	  (flags2str): New function for debugging.
-	* field.c (get_field): Add new var that is like Nnull_string but
-	  does not have numeric attributes, so that new fields are strings.
-	  (set_record): Turn off PERM flag before unrefing fields and field 0.
-	* array.c (in_array): Always evaluate subscript, could have
-	  side effects.
-	* builtin.c (do_strftime): Way increase size of buffer to make sure
-	  we don't have overflow problem. Keeps Paul Eggert happy.
-	* custom.h [__amigaos__]: Define fork to vfork. From Fred Fish.
-	* dfa.c: Move include of config.h to top, for RSXNT. From Kai
-	  Uwe Rommel.

-
-	* io.c (mmap_get_record): Fix return value if file ends without
-	  record separator.
-
-Fri Jan  3 19:57:16 1997  Pat Rankin  <rankin@eql.caltech.edu>
-
-	* awk.y (get_src_buf):  Test for an empty source file by detecting
-	  an initial read of 0 bytes rather than by relying on info from

-Wed Dec 25 11:25:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Release 3.0.2: Release tar file made.
-
-Wed Dec 25 11:17:32 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Makefile.in (install, uninstall): Use $(srcdir)/patchlevel.h.
-	  Thanks to Richard Levitte, LeViMS@stacken.kth.se.
-	  (install): Remove chmod command; let $(INSTALL_PROGRAM) use -m.
-
-Mon Dec 23 20:36:59 1996  Pat Rankin  <rankin@eql.caltech.edu>
-

-
-Fri Dec 20 08:59:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* getopt.c, getopt1.c: Comment out the `#if defined (_LIBC) ||
-	  !defined (__GNU_LIBRARY__)' and `#endif' to force use of this
-	  getopt, even on systems like Linux.  This will be handled
-	  better in 3.1 / glibc 2.
-
-Thu Dec 19 22:52:39 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.y (yylex): In several places, after yyerror(), add call to
-	  exit(). Otherwise, infinite messages. This should probably
-	  be handled better.
-
-Wed Dec 18 22:42:10 1996  Darrel Hankerson  <hankedr@mail.auburn.edu>
-
-	* getopt.c (_getopt_internal): If 'W' and ';', if optind == argc,

-	* aclocal.m4 [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
-
-Tue Dec 17 22:23:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (do_strftime): Fix case if format string is "".

-
-Sun Dec  8 07:53:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Makefile.in (gawk): Took COMPFLAGS out of link line for help
-	  on VMS posix. Shouldn't (I hope) affect anything else.
-
-Thu Nov 28 11:52:24 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* configure.in (AC_PROG_INSTALL): Set INSTALL to install-sh.

-Sun Nov 24 22:16:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (do_printf): If no args, fatal error. Return silently
-	  if --traditional.
-
-Thu Nov  7 20:54:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (inrec): Make sure EOF hasn't already happened before
-	  trying to read; prevents accessing freed buffer. Thanks to
-	  Michal Jaegermann.
-	* Makefile.in [AWKSRC]: Add random.h.
-	* random.h: New file, redefines names of the `random' functions.
-	* random.c, builtin.c: Add include of random.h.

-Thu Nov  7 09:06:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.y (snode): Undo 4 Oct change, put do_split code back.
-	* field.c (do_split): Restore old code; add test for CONST, so
-	  that re_parse_field is used if third arg to split is a regexp
-	  constant.
-
-Mon Nov  4 12:57:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* main.c (main): Research -m[fr] options don't need literal '='
-	  characters. Brian's documentation was confusing.  Fixed, not
-	  that anyone actually uses these options with gawk.
-
-Sun Nov  3 11:23:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* field.c (def_parse_field): Add \n to list of acceptable white space.

-Tue Oct 22 21:27:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c [GAWK_RANDOM_MAX]: Try to make definition a bit
-	  smarter; don't use RAND_MAX if it's equal to SHRT_MAX, blows
-	  things up.
-
-Tue Oct 22 08:49:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* main.c (copyleft): Update copyright date to 1996.

-
-Wed Oct 16 21:32:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (format_tree): Change initial buffer size to 512
-	  and use a constant. Allows large values of %f per bug report
-	  from sheyn@cs.bu.edu.
-
-Wed Oct 16 21:22:08 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

-
-Sun Oct  6 21:57:34 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* re.c (make_regexp): Fixed to handle \8 and \9 in the middle
-	  of a regexp.
-
-Fri Oct  4 10:26:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.y (snode): Remove case for do_split; always making the
-	  third arg a Node_regex is wrong.
-	* field.c (do_split): Rationalized to distinguish `/ /' from `" "'.
-	  Generally fixed up.
-	* node.c (parse_escape): Allow single digit \x escapes.
-
-1996-10-02  Paul Eggert  <eggert@twinsun.com>
-
-	* builtin.c (format_tree): Fix bug in %d and %i format: NaNs, and
-	  values in the range LONG_MAX+1 .. ULONG_MAX, were mishandled.
-	  Don't assume that double values <= -1 are converted to unsigned
-	  long in the expected way; the C Standard doesn't guarantee this.
-
-1996-10-02  Paul Eggert  <eggert@twinsun.com>
-
-	* awk.h (INT_MAX): Remove unused symbol.
-
-Mon Sep 30 22:19:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* getopt.c (_getopt_internal): If 'W' is in the optstring followed
-	  by a ';' then search through the long opts table. This makes
-	  `-W foo=bar' same as `--foo=bar'.
-	* main.c (main): 'W' now prints an error message.
-	  (gawk_option): Deleted the routine.
-
-Sun Sep 29 23:04:54 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (sub_common): Fix several bugs with gsub when

-
-Fri Sep 20 17:35:54 1996  Pat Rankin  <rankin@eql.caltech.edu>
-
-	* alloca.c (NULL): Don't define if <config.h> has already done so.
-
-Fri Sep 20 11:54:31 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (do_print): Evaluate all the expressions first and

-	  for an example.
-
-Tue Sep 10 06:21:40 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.h [FUNC]: New flag, marks a Node_parameter_list as really
-	  being the function name; allows more checking in awk.y.
-	* awk.y (isassignable): Now takes a NODE * instead of a type, to
-	  check if a function parameter is marked FUNC, then it's the function
-	  name, which is not assignable. Fix call from snode().
-	  (function_prologue): Mark function name as FUNC.
-	  (yyerror): Don't call exit() anymore; gawk will now report
-	  all syntax errors.
-
-Sun Sep  1 19:36:30 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* field.c (rebuild_record): After building new field 0, go through
-	  all old fields, and if they used to point into the old one,
-	  have them point into the new one.  Then turn off PERM flag before
-	  unref-ing field 0.
-
-Wed Aug 28 19:13:34 1996  Arnold D. Robbins  <arnold@math.utah.edu>
-
-	* eval.c (set_IGNORECASE): Correctly parenthesize bit operations

-	  change in GNU Coding Standards from RMS.
-
-Sun Aug 11 23:13:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Makefile.in (install): Correct use of $(INSTALL_PROGRAM).
-
-Thu Aug  8 23:29:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* parse.y (isassignable): New function, checks in type can
-	  be assigned to.
-	  (snode): Changed checking for 3rd arg of gsub to be more
-	  general, supersedes earlier change.
-
-Thu Aug  8 13:58:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* parse.y (snode): If third arg to sub or gsub is builtin
-	  function, complain, since can't substitute into result.
-	* eval.c (r_get_lhs): Diagnose Node_builtin as an error, instead
-	  of falling through into default case and using cant_happen().
-
-Thu Aug  1 07:13:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* regex.h [RE_DEBUG]: New macro.
-	  [RE_SYNTAX_GNU_AWK]: Add RE_DEBUG.
-	  [RE_SYNTAX_POSIX_AWK]: Add RE_INTERVALS.
-	* regex.c (re_set_syntax): Add #ifdef DEBUG code to turn on `debug'
-	  flag if RE_DEBUG set, and turn off debug if not set and debug
-	  was on.
-	* main.c (main): Remove `do_intervals = TRUE' from `if (do_posix)',
-	  it's now handled in the definition of RE_SYNTAX_POSIX_AWK.
-
-Mon Jul 29 17:49:07 1996  Pat Rankin  <rankin@eql.caltech.edu>
-
-	* io.c (O_ACCMODE): Define it if <fcntl.h> doesn't.
-
-Mon Jul 29 12:02:48 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* eval.c (set_IGNORECASE): Made somewhat smarter. gawk -v IGNORECASE=0
-	  was acting the same as -v IGNORECASE=1. Thanks to Darrell Hankerson
-	  for the bug report.
-
-Fri Jul 26 12:04:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.h (format_val): Add declaration of new routine.
-	* node.c (format_val): New routine, abstracts old guts of
-	  r_forcestring; accepts format string and index as additional params.
-	  (r_force_string): Changed to call format_val.
-	* builtin.c (do_print):  Don't tree_eval the tree twice in case
-	  OFMTidx != CONVFMTidx; doing so could cause side effects
-	  (from bug report by Tobias Rettstadt, xassp@ipds.uni-kiel.de).
-	  Instead, call format_val.
-
-Mon Jul 22 21:59:15 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (iop_close): Change check for "is $0 in the input buffer"
-	  to use `< (iop->buf + iop->secsiz + iop->size)' instead of
-	  `< iop->end'. The latter is bogus if EOF has been hit on the
-	  file.  Fix from Darrel Hankerson based on bug report by
-	  Charles Howes (howes@grid.direct.ca).  See test/eofsplit.awk.
-
-Thu Jul 18 19:43:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (sub_common): Backed out change of Feb 14 in favor of:
-	  (do_gensub): Changed to use make_string and then to |= TEMP
-	  flag, based on bug report and patch from Katsuyuki Okabe,
-	  hgc02147@niftyserve.or.jp.
-
-Thu Jul 18 19:23:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* custom.h: Added ifdef for QNX, based on bug report from
-	  Michael Hunter, mphunter@qnx.com.
-
-Mon Jul 15 09:31:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (redirect): When finding the rp pointer, if it's not
-	  NULL, set str = rp->value. This gets the '\0' terminated
-	  version. Motivated by bug report from John Hawkinson
-	  (jhawk@bbnplanet.com).
-
-Sun Jul 14 18:40:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* configure.in: Added call to AC_CHECK_LIB(m, fmod), since
-	  apparently some systems have fmod in the math library.
-	  Portability: The Holy Grail.  Sigh.
-
-Sun Jul 14 18:08:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* awk.h: Add Jim Meyerings ISASCII etc hacks for ctype macros.
-	* builtin.c (do_toupper, do_tolower, sub_common): Changed to use
-	  upper-case versions of ctype macros.
-	* main.c (main): Ditto.
-	* node.c (r_force_number, parse_escape): Ditto.
-
-Sun Jul 14 06:34:18 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* field.c (set_record): Made it always do the PERM flag.
-	  Fixes cases where $0 is assigned to, e.g. by gsub, keeps
-	  the fields valid.
-	  (get_field): Removed the call to reset_record in
-	  case where ! field0_valid. We want to leave the fields alone
-	  if they've been changed.
-
-Thu Jul 11 23:04:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (devopen): Change tests of (flag & O_fooONLY) to
-	  (flag & O_ACCMODE) == O_fooONLY. Per (long standing) bug
-	  report from Chapman Flack.
-	  (close_redir): Change final conditional to just (status != 0)
-	  so that ERRNO always set; the warning had its own `if (do_lint)'
-	  anyway.
-	* eval.c (do_split): Force type of array to be Node_var_array
-	  instead of Node_var.  Per (long standing) bug report from
-	  Chapman Flack.
-
-Thu Jul 11 22:17:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Makefile.in (install): Added symlink of gawk to awk if
-	  no awk in $(bindir).
-	  (LN_S): New variable for symlinking.
-	  (uninstall): Remove awk if it's the same gawk.
-	* Configure.in: Added call to AC_PROG_LN_S for Makefile.in.
-
-Sun Jul  7 15:47:13 1996  Arnold D. Robbins  <arnold@infographix.com>
-
-	* main.c (main): Made `--posix' turn on interval expressions.
-	  Gawk now matches its documentation. (What a concept!)
-
-Wed Jul  3 15:02:48 1996  Arnold D. Robbins  <arnold@infographix.com>
-
-	* regex.h, regex.c: Upgraded to changes from Emacs 19.31.
-
-Fri May 17 08:46:07 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (get_a_record): Added `continued' flag. Fix from
-	  Darrell Hankerson for when RS = "\n|something".
-
-Wed May 15 02:34:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Makefile.in (awklib/all): Now depends on gawk, fixes problem
-	  with parallel make.
-
-Tue May 14 15:02:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (format_tree): Fix handling of '*' to deal with
-	  negative value for fieldwidth -- make positive and turn on
-	  left justify. Per bug report from Michael Brennan.
-
-Sun May 12 20:42:06 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* eval.c (r_get_lhs): case Node_subscript. Check if array name
-	  is actually a function, fatal error if so.
-
-Sun May  5 10:11:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (redirect): Call flush_io() before creating a new output pipe,
-	  per bug report from Brian Kernighan (bwk@research.bell-labs.com).
-
-Fri Mar 15 06:38:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* Makefile.in (install): Use $(INSTALL_PROGRAM), not $(INSTALL).
-	  (local-distclean): Add `*~' to list of files to be removed.
-	  (CFLAGS): Now contains just @CFLAGS@.
-	  (COMPFLAGS): Replaces use of CFLAGS, has CFLAGS plus all the
-	  other stuff.
-
-Wed Mar 13 14:19:38 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (mmap_get_record): Fixed to not place sentinel at end
-	  of mmap'ed object. Won't work if file is exact multiple of
-	  disk block size. See comments in code for more info.
-	  Thanks to Rick Adams (rick@uunet.uu.net) for help in testing.
-
-Sun Mar 10 22:50:23 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* io.c (do_close): Notice if we were called as `close(FILENAME)'
-	  and arrange to close the current input file. This turns out
-	  to be easy to do, just call `nextfile(TRUE)'. Based on bug report
-	  from Pascal A. Dupuis, <dupuis@lei.ucl.ac.be>.
-
-Thu Mar  7 08:08:51 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* field.c (init_fields, grow_fields, set_field, rebuild_record):
-	  Nuke the `nodes' array everywhere.  Anytime a field is unref'ed,
-	  allocate a new node that is a copy of Nnull_string. This avoids
-	  subtle memory management problems when doing a lot of assignment
-	  to fields, and tweaking of NF. Make sure that fields_arr[0] always
-	  has a type of Node_val!
-	* field.c (set_NF): If NF is decremented, clear fields between
-	  NF and parse_high_water, otherwise if NF incremented, clear
-	  fields between parse_high_water and NF.
-	* eval.c (nodetype2str): New function, used for diagnostics.
-	  (interpret): Use nodetype2str when finding invalid node.
-
-Mon Mar  4 09:02:28 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (do_toupper, do_tolower): Use isascii along with
-	  isupper/islower before changing case, in case characters have
-	  the high bit set. This is a hack.
-
-Mon Feb 26 22:24:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
-
-	* builtin.c (sub_common): If no match, and called from gensub,
-	  don't free the temporary string, since the tmp_number then

+Mon Jan  5 23:07:58 2009  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (devopen): Add a retry to calls to socketopen. Tunable
+	via undocumented GAWK_SOCK_RETRIES environment variable. Based
+	on code from Juergen Kahrs <Juergen.Kahrs@vr-web.de> after a
+	suggestion from Hermann Peifer <peifer@gmx.eu>.
+
+Mon Jan  5 22:48:39 2009  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (redirect): A getline from a directory is no longer
+	fatal; instead it returns -1. Thanks to Paolo <oopla@users.sf.net>
+	for the report.
+
+Mon Dec 29 22:04:57 2008  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* builtin.c (format_tree): Case for 's', improve logic for setting
+	the number of characters to copy, also at pr_tail. Based on
+	bug report by Hermann Peifer <peifer@gmx.net>.
+
+Thu Dec 11 21:23:50 2008  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* builtin.c (do_length): If the wide string has zero length
+	but the bytes are more than zero, use the number of bytes.
+	(do_index): Similar also: fall back to byte count if the
+	bytes don't make a wide-character string.
+	Bug reported by "Carlos G." <charlie.brown.uy@gmail.com>
+
+	(do_substr): If defaulting to length of rest of the string,
+	do it based on the wide char string if it's valid.
+
+Fri Dec  5 11:12:11 2008  Arnold D. Robbins  <arnold@skeeve.com>

+	to have crept back into the code in the August 2007 merge with
+	GNU grep. Sigh.)

+	integral values that are outside the range of a long. Thanks to
+	Hermann Peifer <peifer@gmx.eu> for pointing out the existence
+	of a problem.
+
+Fri May 23 12:08:24 2008  Arnold D. Robbins  <arnold@skeeve.com>

+	is integral by trying to convert back to floating point and seeing
+	if the value matches.  This is more robust than trying to test
+	whether the floating-point value is representable as an integer.

+	* field.c (set_FIELDWIDTHS): Fix off-by-one error in assignment
+	of sentinel value at end of FIELDWIDTHS array.
+
+Fri Sep 23 16:05:13 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (read_one_line): New function, mainly for debugging,
+	that reads one line of data at a time to pass back as a buffer.
+	Emulates the variable-length record filesystem of VMS, where
+	we first saw the problem fixed here.
+	(get_src_buf): New variable `readfunc' which is a pointer to a
+	function implementing the `read' system call interface. Based on
+	an environment variable, use `read_one_line' instead of `read'
+	for testing.   Make the test for expanding the buffer smarter,
+	so that it doesn't grow unnecessarily.
+
+	Thanks to Galen Tackett (tackett_galen@bah.com) for reporting
+	the problem and to Anders Wallin and Pat Rankin for help
+	tracing and reproducing the problem and testing the fix.
+
+Fri Sep  9 15:06:07 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* hard-locale.h (xmalloc): Move declaration to file scope
+	for non-glibc systems and gcc 4. Thanks to Kito Danya Dietrich
+	<kito@gentoo.org>.
+
+Thu Aug 25 22:40:40 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regcomp.c (build_range_exp): Avoid `btowc' for single-byte
+	characters. Fedora Core 2, maybe others, have a broken version
+	that can't handle values > 127.
+
+Fri Aug 19 16:13:28 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regexec.c (proceed_next_node): Added a band-aid check at the
+	top of the first `if' to make sure that `mctx->state_log[*pidx]'
+	isn't NULL.
+
+Fri Aug 12 13:10:33 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (iop_alloc): Only free `iop' if it was malloc'ed in
+	the first place.
+
+Tue Jul 26 21:46:16 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* Release 3.1.5: Release tar file made.
+
+Tue Jul 26 21:44:54 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Copyright dates on all relevant files updated to 2005.
+
+Wed Jul  6 17:09:02 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Minor cleanups:
+
+	* io.c (do_index): Remove unused variables `mbclen', `mbs1' and `mbs2'.
+	* node.c (wstrstr): Remove unsed variable `j'.
+	(dump_wstr): `#ifdef' out, not currently needed.
+	* eval.c (op_assign): Move decl of `t1' and `t2' into a separate block
+	for the `! HAVE_FMOD' case. Keeps the compiler quiet. Similar for
+	`ltemp'.
+
+Wed Jul  6 16:51:31 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (close_io): Now takes pointer to boolean parameter indicating
+	if there was a problem closing standard output or standard error.
+	Update it in the right places.
+	* awk.h (close_io): Update the declaration.
+	* main.c (main): New variable `stdio_problem'. Pass it to `close_io'.
+	Check the result and exit non-zero if there was a problem.
+	(usage, version): Print warning message if problems with stdout.
+
+	Unrelated:
+
+	* main.c (main): For call to `setlocale' for LC_MESSAGES, just use
+	`#ifdef LC_MESSAGES'.  Per Bruno Haible <bruno@clisp.org>.
+
+Wed Jul  6 16:44:58 2005  Jim Meyering  <jim@meyering.net>
+
+	* main.c (init_fds): If any of the STDIN_FILENO, STDOUT_FILENO,
+	STDERR_FILENO are initially closed, reopen them with permissions
+	contrary to common usage so that any reasonable attempt to use
+	them will evoke the same sort of error as reading or writing to
+	a closed file descriptor would.
+
+Mon Jul  4 09:38:29 2005  Arnold D. Robbins  <arnold@skeeve.com>
+
+	More multibyte fixes from Kimura Koichi, <kimura.koichi@canon.co.jp>.
+
+	* node.c (format_val, r_dupnode): Spell `wstptr' correctly.
+	* regex_internal.c (build_wcs_upper_buffer): Label `offsets_needed'
+	should not be inside `#ifdef _LIBC'.
+	* regcomp.c (build_charclass): Fix declaration of `class_name' in
+	prototype to not be unsigned.
+
+Thu Jun 30 11:52:34 2005  Arnold D. Robbins  <arnold@skeeve.com>

+	* profile.c (tree_eval): Node_not: Remember to print the exclamation
+	point!  Thanks to Dan Nielsen <Dan.Nielsen@corporate.ge.com>
+	for the bug report.
+	* mbsupport.h: Fix spelling of HAVE_ISWUPPER. Thanks to

+
+	Unrelated changes:
+
+	* builtin.c (do_length): Allow array argument to length().
+	Returns number of elements in array.
+
+	* awkgram.y (yylex): Ignore carriage returns in source code. Sigh.
+
+Wed Jun 15 22:12:15 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* node.c (isnondecimal): Check loc.decimal_point before using it.
+	Avoids problems with command line assignment when locale info may
+	not be set up all the way yet.
+
+Wed Jun 15 21:59:54 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* node.c (make_str_node): If working with multibyte characters, while
+	parsing string constants, keep multibyte characters together. This
+	avoids problems in cases where one of the bytes is backslash. Initial
+	patch supplied by Kimura Koichi, <kimura.koichi@canon.co.jp>.
+
+Tue Jun 14 21:50:37 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>
+
+	Use Exponentiation By Squaring for integer powers for ^ and ^=.

+
+Fri Jun  3 12:15:54 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac: Further change the hack at the end so that
+	it works on Mac OS X `sed'. Sigh.
+
+Thu Jun  2 22:44:01 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac (TYPE_SOCKLEN_T): Use `int' as default type if can't
+	figure one out.
+	* awkgram.y: Warn that `//' is not a C++ comment. (:-)
+
+Thu Jun  2 20:55:27 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	From: Benno Schulenberg <benno@nietvergeten.nl>
+
+	* eval.c (func_call): Take message out of gettext call since it's for
+	debugging.
+	* ext.c (get_actual_argument): Fix formatting of message.
+
+Wed May 25 09:19:37 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac: Change hack at end that fixes Makefile to keep
+	version.c to use `sed' and not `ed'. More portable to OS/2, probably
+	other systems.
+
+Mon May 23 09:01:26 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	Portability help from Jim Meyering.
+
+	* io.c: Rework ifdefs for <inttypes.h> and <stdint.h>. Test them

+	Check for isascii and btowc for regex.
+
+Sat May 14 22:49:54 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* wait_any (errno): Remove decl.
+	* gawk_popen: The pipe-simulated but not VMS or DOS version. Remove
+	decl/use of `strdup' in favor of `emalloc' and `strcpy'.
+
+Wed May 11 18:33:30 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	All files: Updated address of FSF to:
+
+	51 Franklin Street, Fifth Floor
+	Cambridge, MA  02110-1301
+
+Wed May 11 18:19:03 2005  Jim Meyering  <jim@meyering.net>
+
+	* configure.ac: Use AM_GNU_GETTEXT([external]).
+	Reflect upgrade to gettext-0.14.4.
+	Reflect renaming of `jm_'-prefixed macros.
+	(AC_CONFIG_FILES): Remove intl/Makefile.
+
+	* Makefile.am (SUBDIRS): Remove intl.
+	(AM_CPPFLAGS): Remove -Iintl.
+
+Wed May 11 11:42:06 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	Straighten out mess with `isblank' which is C99 <ctype.h> function.
+
+	* configure.ac: Remove check for `isblank' in call to AC_CHECK_FUNCS.
+	* regex_internal.h: #ifdef out definition of `isblank' and provide
+	`is_blank' function a la dfa.c.
+	* field.c: Ditto.
+	* regcomp.c: #ifdef use of `isblank' and add `is_blank' use instead.
+
+Mon May  9 08:29:37 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac: Add type check for `socklen_t', fixes compile
+	warning on AMD/64 Linux.
+	* io.c (socketopen): Change type of socket length variables
+	to `socklen_t' from `size_t'.
+
+Thu May  5 22:00:03 2005  John E. Haque <j.eh@mchsi.com>
+
+	* io.c (iop_alloc): Let an input processor hook installed via
+	`register_open_hooks' open its own fd in case gawk does not know
+	how to open it.
+	(iop_open): Call `os_close_on_exec' after `iop_alloc'.
+	ADR: If `iop_alloc' returns NULL but the fd is valid, close
+	the fd to avoid an fd leak.
+
+Mon May  2 08:05:59 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* eval.c (update_ERRNO): Don't use `return' in a `void' function.
+	* awk.h (AWKNUM): Back out use of `long double' based on LDBL_MANT_DIG.
+	* builtin.c (tmp_integer): Back out extra ifdefs.
+
+Fri Apr 29 13:01:05 2005  Arnold D. Robbins    <arnold@skeeve.com>

+	* field.c: Add define for `isblank' if we don't have it.
+
+Fri Apr 29 12:01:33 2005  Julian Foad  <julianfoad@btopenworld.com>
+
+	From grep.  Doesn't seem to affect awk.
+
+	* dfa.c (lex): Fix bug #9519: "echo do^re | grep do^re" was
+	failing to find a match. [Towards end, set `lasttok' before
+	returning `c'.]
+
+Fri Apr 29 00:28:46 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac: Jump through an amazingly convoluted hoop to get
+	config.status to keep version.c upon `make distclean'. Seems to
+	work though.
+
+Thu Apr 28 23:40:02 2005  Stepan Kasal  <kasal@ucw.cz>
+
+	* configure.ac (PRINTF_HAS_F_FORMAT): Some cosmetic changes.
+	(custom.h): Don't cat custom.h at the end of config.h; instead, use
+	AH_BOTTOM([#include "custom.h"])
+	* awklib/Makefile.am (AM_CPPFLAGS): Add $(top_srcdir) so that
+	custom.h can be found.
+
+Thu Apr 28 23:21:22 2005  Jim Meyering  <jim@meyering.net>
+
+	* field.c (set_FIELDWIDTHS): Tighten up the code to accept FIELDWIDTHS
+	values in [1..INT_MAX], e.g., detect overflow and invalid strings,
+	and reject strings starting with `-'.
+
+Thu Apr 28 23:05:33 2005  Stepan Kasal  <kasal@ucw.cz>
+
+	* dfa.c (parse_bracket_exp_mb): Shorten one part of the code, to get
+	closer to grep's copy.
+
+Thu Apr 28 23:00:58 2005  Pat Rankin    <rankin@pactechdata.com>
+
+	* builtin.c (format_tree) [#if VAXCRTL]:  For floating point
+	formatting, reject zero_flag if using old VAXCRTL run-time
+	library to avoid getting erroneous results which appear as if
+	numerically incorrect (due to an embedded space in some cases,
+	extra trailing zeroes in others) rather than just misformatted.
+	`hsprint' test still fails, but not as badly.
+
+Thu Apr 28 19:12:03 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* re.c (reflags2str): Add three new RE_ flags from current regex.h
+	to bring the table up to date.
+
+	* builtin.c (format_tree): Save 2 spare bytes instead of one. Suggested
+	by Stepan Kasal.
+
+Thu Apr 28 18:16:09 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>
+
+	* awk.h (IOBUF): Add new fields `opaque', `get_record', and
+	*close_func', to support insertion of an alternate input processor.
+	This is used by the XML extension.
+	(register_deferred_variable, register_open_hook, update_ERRNO_saved):
+	Declare new functions.
+	(load_environ, load_procinfo): Remove declarations -- these functions
+	are no longer global, since we use register_deferred_variable instead.
+	* awkgram.y (register_deferred_variable): New function to allow
+	calling code to register special variable names that trigger a callback
+	upon the first reference.  This is now used to implement ENVIRON
+	and PROCINFO.
+	(variable): Search the list of deferred variables instead of hardcoded
+	tests for ENVIRON and PROCINFO.
+	* eval.c (set_BINMODE): Fix spelling of "arbitrary" in warning message.
+	(update_ERRNO_saved): New function that allows the caller to specify
+	the errno value instead of using the current value.
+	(update_ERRNO): Implement by calling update_ERRNO_saved(errno).
+	* io.c (iop_close): Call `iop->close_func' if non-NULL.
+	(close_redir): Should save `errno' value, otherwise `lintwarn' messages
+	might update it.  Then use `update_ERRNO_saved' to set ERRNO.
+	(do_getline): Call `update_ERRNO_saved' to set ERRNO based on the
+	error code returned by the redirect function (instead of the current
+	value of errno).  Similarly, use `update_ERRNO_saved' to set ERRNO
+	based on the value returned by `get_a_record'.  But add a special
+	check to avoid updating ERRNO if `get_a_record' returns an error
+	code value of -1 (this is used by the XML extension which already
+	sets ERRNO before returning).
+	(register_open_hook): New function to register a function to be
+	called whenever a new data file is opened.  This can be used to
+	install a special input processor (as in the XML extension).
+	(iop_alloc): Call registered open hook.
+	(get_a_record): If a `get_record' method has been set, call that instead.
+	* main.c (init_vars): Use `register_deferred_variable' to implement
+	ENVIRON and PROCINFO.
+	(load_environ, load_procinfo): Now static instead of global.
+	* doc/gawk.texi: Document new internal functions `update_ERRNO_saved',
+	`register_deferred_variable', and `register_open_hook'.
+
+Thu Apr 28 10:50:10 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	* array.c (assoc_find, do_delete): Change incorrect uses of STREQN
+	to memcmp.
+	* builtin.c (do_index): Same.
+	* field.c (set_FS): Same.
+	* io.c (redirect, getredirect, do_close, set_RS): Same.
+	* re.c (reisstring): Same.
+
+Wed Apr 27 21:35:57 2005  Arnold D. Robbins    <arnold@skeeve.com>
+
+	Allow for long double. Initial changes from  Jean-Marc Saffroy
+	<jean-marc.saffroy@ext.bull.net>.
+
+	* awk.h (AWKNUM): If have long doubles (LDBL_MANT_DIG), define AWKNUM
+	as long double, otherwise just use double.
+	* builtin.c (format_tree): Change type of tmpval to double.
+	(do_strtonum): Same for `d' and types used in casts.
+	(tmp_integer): Don't do bit shifting if have long doubles.
+
+	Unrelated, from Andrew J. Schorr:
+
+	* io.c (close_one): Check for RED_FILE|RED_WRITE, not just RED_FILE.
+
+Mon Apr 25 12:23:18 2005   Andrew J. Schorr	<aschorr@telemetry-investments.com>
+
+	* eval.c (r_tree_eval): In Node_assign_concat case, when copying string
+	constants, include the terminating zero byte.
+
+Fri Apr  1 06:26:31 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Update to Automake 1.9.5.

+
+	* builtin.c (do_tolower, do_toupper): Remove old code
+	based on 8-bit character table.
+
+Wed Feb 23 08:23:22 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* bisonfix.awk: New file, fixes continued #ifdef for dumb compilers.
+	* Makefile.am (awkgram.c): Fix rule to use it.

+	* random.c: Here.  Move include of random.h back to where it was.
+
+	* regcomp.c, regex.c, regexec.c: NUKED all use of alloca not inside
+	`_LIBC' ifdef. Hooray!
+
+Sat Feb 19 20:13:28 2005   Pat Rankin    <rankin@pactechdata.com>

+	[ER_ERRMSG, ERRMSG_TYPE, ERRMSG_OFFSET, ERRMSG_SEPARATOR]: New macros
+	  conditionalized upon gawk's NO_TOKEN_PASTING macro.
+	* regcomp.c: Use them.
+	(parse_dup_op): Use alternate initialization of start_token if
+	  RE_TOKEN_INIT_BUG is defined.
+	* regexec.c (proceed_next_node): Compare push_fail_stack() result
+	  explicitly against REG_NOERROR rather than implicitly against 0.

+
+	* node.c (unref, format_val): Add assertions checking that both

+
+Thu Feb 10 15:48:48 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* regex_internal.c (re_dfa_add_node): Remove variable `type'
+	and just use `token.type' directly in RE_ENABLE_I18N code below.
+	Saves a compiler warning, and a good compiler will handle it anyway.
+	* regexec.c (check_arrival_add_next_nodes): Move decl of `err'
+	inside #ifdef RE_ENABLE_I18N code where it's used.

+
+Tue Feb  8 19:26:22 2005   Pat Rankin  <rankin@pactechdata.com>
+
+	* regcomp.c (init_dfa): Avoid strcasecmp() since regex.c doesn't

+
+	* main.c (main):  Call `close_io', without its result affecting
+	the exit status.  Super small, super dark corner.
+
+	See test/exitval2.awk.
+
+Tue Feb  1 11:58:29 2005   Arnold D. Robbins    <arnold@skeeve.com>

+
+	Reinstate patch of 18 Nov 2001, for VMS, at least:
+
+	* random.c (srandomdev): ifdef-out.  Lots of compile time
+	  problems on multiple platforms, and gawk doesn't even
+	  use the routine.  The heck with fine-grained solutions.
+
+Thu Jan 20 14:15:32 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* awkgram.y (LEX_FOR): Free NAME tokens in transformation of
+	`for (iggy in foo) delete foo[iggy]' into `delete foo'.
+	Thanks and a tip of the hatlo to Valgrind.
+
+	* dfa.c (_): Clean up stuff here by just including "gettext.h".
+	Per Bruno Haible.
+
+Wed Jan 19 18:29:23 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* awkgram.y (yylex): Improve parsing of numeric constants
+	and hex values, via a push from Paul Eggert. See test/hex.awk.
+
+	* regex_internal.c (re_node_set_alloc): If `size' is 0, just
+	zero out the structure. From valgrind.
+
+Tue Jan 18 17:23:25 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Make gawk multibyte aware.  This means that index(), length(),
+	substr() and match() all work in terms of characters, not bytes.
+
+	* awk.h (NODE): Add `wsp' and `wslen' elements to value for wide
+	string.
+	(WSTRCUR, wstptr, wstlen, force_wstring): New macros.
+	(str2wstr, wstrstr, wcasestrstr): New declarations.
+	* builtin.c (do_index, do_length, do_substr, do_match): Handle wide
+	strings.
+	* eval.c (flags2str): Add WSTRCUR.
+	* node.c (format_val, r_dupnode, mk_number, make_str_node, unref):
+	Add code to deal with wide strings.
+	(str2wstr, dump_wstr, wstrstr, wcasestrstr): New functions.
+
+Sun Jan 16 15:10:35 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* random.h (int32_t): Define this type.
+
+Thu Jan 13 14:38:13 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Cause `configure --disable-nls' to still allow locale-correct
+	formating of numeric values.
+
+	* builtin.c (format_tree): Change #ifdefs to only test HAVE_LOCALE_H.
+	Improve code for ' flag so that extraneous separator is not included if
+	number of digits is multiple of locale separater count (3, 6, 9, etc.)
+	* dfa.c (dfaparse): Change ifdef to only test #ifdef LC_COLLATE.
+	* eval.c (fmt_ok): Remove ENABLE_NLS from #ifdef test.
+	* gettext.h: Include <locale.h> on both sides of test. Should really
+	be factored out.
+	* main.c (loc): Remove ENABLE_NLS from #ifdef test.
+	(main): Same in call to localeconv().
+	* node.c (isnondecimal): Remove ENABLE_NLS from #ifdef test.
+
+	Unrelated:
+
+	* regcomp.c (init_dfa): Change `codeset' to `codeset_name' in two
+	places.
+
+Mon Jan 10 11:49:56 2005   Arnold D. Robbins    <arnold@skeeve.com>
+

+Thu Jan  6 16:44:32 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Improve autoconfiscation stuff for wide character use.
+
+	* builtin.c (do_tolower, do_toupper): Conditionally compile
+	call to `wide_tolower_toupper'.
+	(wide_tolower_toupper): Conditionally compile typedefs and function.

+
+	Unrelated change:
+
+	* hard-locale.h (hard_locale): Add decl of `xmalloc' to prevent

+
+Wed Jan  5 10:20:17 2005   Arnold D. Robbins    <arnold@skeeve.com>

+
+Tue Jan  4 18:47:56 2005   Arnold D. Robbins    <arnold@skeeve.com>
+

+
+	* alocal.m4, config.guess, config.sub, install-sh: Updated.
+
+Mon Jan  3 14:08:27 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Update to Automake 1.9.3.
+
+	* INSTALL, alocal.m4, config.guess, config.sub, depcomp,
+	install-sh, missing, ylwrap: Updated.
+
+Mon Jan  3 11:23:36 2005   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Fix obscure issue. ^ in RS should only match at the very
+	beginning of the input.  Essentially, the file is one long
+	string.  To do this, use the `not_bol' flag in the `struct
+	pattern_buffer'.  Thanks to Stepan Kasal for pointing out the
+	problem and to Andreas Schwab for pointing out the mechanism
+	for a solution.
+
+	* awk.h (RE_NEED_START, RE_NO_BOL): New flags for `research'.
+	(IOP_AT_START): New flag for IOBUF.
+	(research): Last parameter is now `flags'.
+	* builtin.c (do_match, sub_common): Change calls to `research'.
+	* eval.c (interpret, match_op): Same.
+	* field.c (re_parse_field): Same.
+	* io.c (spec_setup): Add IOP_AT_START flag.
+	(iop_alloc): Same.
+	(rsrescan): Modify logic to check IOP_AT_START and if not on to
+	add RE_NO_BOL to flags value in call to `research'.
+	(get_a_record): Clear IOP_AT_START upon return from `*matchrec'.
+	(iopflags2str): Add IOP_AT_START to table.  Also IOP_CLOSED,
+	which was missing. (Ooops.)
+	* re.c (research): Last paramater is now flags.  Modify logic to
+	handle RE_NO_BOL case by setting the right bit initially. Clean
+	up control flow so that it's cleared before returning.  If RE_NO_BOL,
+	don't bother with the dfa matcher, as it doesn't have an analogous
+	capability.
+
+Wed Dec 22 12:33:48 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	For --exec, don't allow x=y assignments where filenames would be.
+	Do allow -v.  This is because we assume --exec is used mainly for
+	CGI stuff and we don't want var assigns to affect the code.
+
+	Suggested by Stepan Kasal; motivated by reading about web security.
+
+	* main.c (disallow_var_assigns): New variable.
+	(main): Set the var for --exec.
+	(arg_assign): Check it appropriately.
+
+Sun Dec 19 17:27:09 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* builtin.c (do_gensub): Make `global' flag smarter, such that
+	a string numeric constant (e.g., "3") acts like a numeric
+	constant.
+	* node.c (r_force_number): Not really related: Only set NUMCUR
+	if we actually convert some digits.
+
+Sun Dec 19 16:08:50 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* dfa.h, dfa.c: Synchronize with what's happening in GNU grep
+	development.  Effectively only minor whitespace changes and some
+	slight code motion of ifdefs and includes.
+	* hard-locale.h: New file, extracted from old dfa.c.
+	* Makefile.am (base_sources): Add hard-locale.h.
+
+Sun Dec 19 11:13:45 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* io.c (socketopen): Change type of `readle' and `namelen'
+	variables to size_t.  For QNX, but a good idea anyway. Thanks
+	to `Anthony' (rz1a@mail.ru).
+
+Mon Dec  6 11:11:22 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Undid change of Mar 9 2004, to add gofast patch.  It gets things
+	wrong for gawk.  This removes the bandaid of ifdef-ing out the
+	main check.  Eventually this'll all get straightened out in the
+	GNU grep code.
+
+	* dfa.c (buf_offset): Removed.
+	(SKIP_REMAINS_MB_IF_INITIAL_STATE): Removed use of buf_offset, do
+	free `mblen_buf', `inputwcs'.
+	(match_anychar, match_mb_charset, transit_state_consume_1char,
+	transit_state): Remove use of buf_offset in mblen_buf.
+	(dfaexec): Use `free' and `malloc', not `realloc'.
+
+Mon Dec  6 10:55:37 2004   Fumitoshi UKAI       <ukai@debian.or.jp>
+
+	Forwarded from james@nocrew.org, the Debian contact.
+
+	* dfa.c (parse_bracket_exp_mb): 
+	1. Build range correctly when IGNORECASE for [a-a] to also get 'A'.
+	2. For [:lower:] and [:upper:], if ignoring case, set type string
+	   to "alpha".  This parallels code in the regex routines.
+	3. Reset wc1 to EOF when parsing bracket expressions.
+
+Mon Nov 29 18:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* io.c (redirect): When allocating a new struct redirect, set
+	rp->pid to -1, not 0, so that code checking for EOF on an
+	input pipe works correctly.
+
+Thu Nov 25 14:22:41 2004  Stepan Kasal  <kasal@ucw.cz>
+
+	* Makefile.am (MAINTAINERCLEANFILES): Add.
+	* version.in (version_string): Use PACKAGE_STRING.

+
+	* re.c: Fix a typo in a comment.
+
+Mon Nov 22 16:47:00 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* awkgram.y (yylex): Add lint check for tawk style modifiers on
+	regexes, /.../i and /.../s.  Not that it'll help anyone.
+
+Wed Oct 27 14:25:18 2004  Stepan Kasal  <kasal@ucw.cz>
+
+	* builtin.c (do_tolower, do_toupper): Fix the wide char handling,
+	  especially when the lowercased char doesn't ocuppy the same
+	  number of bytes as its uppercase equivalent.  Make use of ...
+	(wide_tolower_toupper): ... this new static function.
+
+Mon Oct 25 11:51:14 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* builtin.c (bchunk, bchunk_one, cksize): Change type of `olen'
+	to size_t from long.  It is the 21st century now, after all...
+	Thanks to Stepan Kasal.
+
+Mon Oct 11 10:49:09 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* awkgram.y (yylex): Improve lint warnings for non-decimal constants.
+	* node.c (isnondecimal): Made a little smarter, thanks to Stepan Kasal.

+
+	* dfa.c (dfamust): Redo fix of 22 Sep to match code from
+	current GNU grep.
+
+Sun Oct  3 23:06:00 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* node.c (isnondecimal): Made smarter, so that 0xEE does
+	register as non-decimal. Added parameter to indicate use of
+	locale's decimal point and changed declaration and callers.
+
+Tue Sep 28 18:38:17 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* node.c (isnondecimal): New function, now smarter.
+	* awk.h (isnondecimal): Changed from macro to function.
+
+Wed Sep 22 11:24:46 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* dfa.c (dfamust): At end, check results of `malloc'.
+	Based on bug report from Sorav Bansal <sbansal@stanford.edu>
+	for grep.
+
+Mon Sep 20 13:18:18 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	New --exec option.  Needed for gawk CGI scripts to prevent
+	arbitrary options and/or source getting passed in from the web.
+
+	* main.c (optab): New long option, --exec.
+	(main): Catch it.  Like -f but end option processing.
+	(usage): Add it to the usage message.
+
+	Thanks to John DuBois and Don Stokes for their input.
+
+	Unrelated:
+
+	* dfa.c (dfaexec): Disabled caching into buffer that bypasses
+	multibyte initialization, since it can get things wrong. Thanks
+	to Andreas Schwab <schwab@suse.de>.
+
+Mon Sep 20 12:59:42 2004   Andreas Schwab  <schwab@suse.de>
+
+	* awkgram.y (nextc): Check for end of lexer buffer before
+	advancing ring buffer index.
+
+Wed Sep  8 09:54:53 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* main.c (main): Force LC_NUMERIC locale to "C" before parsing
+	the program, since a variable assignment with -v can leave the 
+	locale set incorrectly.
+
+	Thanks to Sirix <sirix@poczta.onet.pl> for reporting the problem.
+
+Wed Aug 25 18:55:30 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* main.c (UPDATE_YEAR): New constant at top of file, where we
+	won't miss it.
+	(copyleft): Use it.
+
+Sun Aug 22 17:26:39 2004   Stepan Kasal  <kasal@ucw.cz>
+
+	Define gawk_mb_cur_max even if there is no mbs support, as
+	``const int'' and assign 1 to it.
+	This fixes a bug in re.c where #ifdef MBS_SUPPORT was missing.
+
+	* awk.h (gawk_mb_cur_max): Declare.
+	* main.c (gawk_mb_cur_max): Define.
+	* awkgram.y (nextc_is_1stbyte): Without mbs support, define to 1.
+	* builtin.c (index_multibyte_buffer): Define a dummy function
+	  when there is no mbs support.
+	* awkgram.y, builtin.c, re.c: Remove some `#ifdef MBS_SUPPORT'.
+
+Sun Aug 15 22:08:04 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	Import current FreeBSD random.c.  Make it work for gawk.
+	Needed for cases where long is more than 32 bits.
+
+	* random.c: Imported from FreeBSD. Header includes tweaked.
+	* random.h: Typdef gawk_uint32_t appropriately and #define uint32_t
+	  to it.
+	* configure.ac: Add calls to AC_CHECK_SIZEOF for unsigned int
+	and unsigned long.
+
+	Started with
+	http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/stdlib/random.c
+	Thanks to Andreas Schwab <schwab@suse.de> for the pointer.
+
+Thu Aug 12 13:09:53 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* main.c (copyleft): Fix copyright year.
+
+Mon Aug  2 12:18:15 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* Release 3.1.4: Release tar file made.
+
+Mon Aug  2 12:17:40 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac: Fix the hack. Do the sed on `Makefile',
+	not `Makefile.in'.  Sigh.
+
+Sun Aug  1 14:48:30 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* configure.ac: MAJOR HACK: At end, remove version.c from Makefile.in
+	variable `CONFIG_CLEAN_FILES' so that `make distclean' doesn't
+	remove version.c.
+
+Mon Jul 19 17:07:27 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* config.guess, config.sub: Updated from Savannah CVS.
+
+Fri Jul 16 10:59:07 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* re.c (make_regexp): Bracket code using `gawk_mb_cur_max'
+	inside `#ifdef MBS_SUPPORT'.
+
+Thu Jul 15 12:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>
+
+	* dfa.c (parse_bracket_exp_mb):  If doing case folding,
+	include the other case for regular characters inside [...].
+
+	* re.c (make_regexp): Smarten up handling of IGNORECASE,
+	particularly for multibyte character sets. Sigh.
+
+Wed Jul 14 16:25:23 2004  John Haque  <mary1john8@earthlink.net>
+
+	* eval.c (interpret): For `Node_K_return', use `copynode'
+	and not `dupnode' for non-PERM, non-TEMP values.
+	(func_call): Don't add TEMP flag to returned value.
+
+	These two fix a problem uncovered by the July 8 change in
+	`assoc_lookup'.
+
+Wed Jul 14 16:14:09 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (node_common): Add check `lexeme >= lexptr_begin',
+	from valgrind run.
+
+Wed Jul 14 16:00:51 2004  John Haque  <mary1john8@earthlink.net>
+
+	* io.c (rsrescan): Fix off by one error at end of record.
+
+Thu Jul  8 16:59:51 2004  Stepan Kasal  <kasal@ucw.cz>
+
+	* awkgram.y (output_redir): Make sure not to dereference NULL
+	  pointer.  The bug was triggered by the following code:
+
+		gawk 'BEGIN{print "date" |& getline}'
+
+	No test case created, beacuse of the following:
+	Correct interpretation involves executing "1" or "0" -- as the user
+	may have defined this, we would have to override this in the test
+	script.  It's not worth the hassle.
+
+Thu Jul  8 12:59:49 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (load_casetable): Name changed from `load_ignorecase'.
+	* eval.c (load_casetable): Name changed from `load_ignorecase'.
+	Fix all uses.

+
+	* awkgram.y (get_src_buf): Fix off-by-one error to avoid "does not end
+	in newline" messages.
+	* array.c (assoc_lookup): Small performance hack: for TEMP subs nodes,
+	use its string memory for ahname.
+	* ext.c (get_actual_argument): Minor code cleanup.
+	* builtin.c (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl):
+	fixed to issue "non-numeric argument" lint warnings before using
+	`force_number'.
+
+Mon Jun 21 16:53:35 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	More changes from John Haque to rationalize extension functions.
+
+	* awk.h (get_curfunc_arg_count): Name changed from

+	* eval.c (get_curfunc_arg_count): Ditto, body redone to count actual
+	args passed at call time.
+	* ext.c (get_argument): Update range check.
+	(get_actual_argument): Simplify the code.
+
+Mon Jun 14 14:01:16 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Changes from John Haque and ADR to rationalize extension functions.
+
+	* awk.h (check_special, get_curfunc_parm_count, get_actual_argument):
+	new function declarations.
+	(get_scalar_argument, get_array_argument): New macros.
+	* awkgram.y (check_special): New function.
+	(yylex): Use `check_special' to search `tokentab'.
+	(dump_funcs): Always count functions, in order to get dynamic ones.
+	Removed bogus use of `static' on `tab' variable.
+	* eval.c (struct fcall): Change type of `count' to `size_t'.
+	(get_curfunc_parm_count): New function.
+	(push_args): Set `r->rnode' to NULL for local variable.
+	* ext.c (make_builtin): Add sanity checking for presence and
+	name of new function, and that it's not a redefinition.
+	(get_argument): Check that requested arg is within range of actual
+	number of parameters.  Also clean up logic for Node_var_new,
+	Node_var_array, Node_array_ref.
+	(get_actual_argument): New function.
+	* profile.c (pp_builtin): Better handling of dynamic extension function.
+
+Sun Jun 13 14:32:22 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (redirect): Conditionalize checking for process recovery
+	on `#ifdef PIPES_SIMULATED'.  Needed for MS-DOS and VMS.
+	* builtin.c (tmp_integer): Change bracketing of magic test to
+	`#ifdef HAVE_UINTMAX_T' which is more general and more correct.
+
+Wed Jun  9 21:36:01 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* re.c (make_regexp): Add dfa matching into IGNORECASE handling.
+
+Tue Jun  8 15:38:56 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (casetable): Remove `const'.
+	* eval.c (casetable): Remove `const'.
+	(load_ignorecase): New function.  Loads locale-correct values in
+	upper 128 bytes.
+	(set_IGNORECASE): Call `load_ignorecase'.
+
+Tue Jun  8 14:04:19 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (get_src_buf): Make sure that value from
+	`optimal_bufsize' is reasonable.  Increase it if not.
+
+Tue Jun  8 13:54:28 2004  John E. Haque      <mary1john8@earthlink.net>
+
+	* awkgram.y (statement:LEX_FOR): Fix bug in loop to `delete a'
+	optimization.

+	* io.c (child_died, child_signo, child_catcher): Removed.
+	(get_a_record): Remove code checking for death of child.
+	(redirect): If `rp' matches and is at EOF and type is input
+	pipe, and `rp->pid' is not -1, call `wait_any' to reap the
+	child.  This is a heuristic, but it works pretty well.
+
+Sun Jun  6 18:35:17 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (get_a_record): Restore use of `memmove' instead of
+	memcpy. Otherwise some tests break on some systems. We think.

+
+Thu Jun  3 14:06:06 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (version_string): Removed declaration, since
+	version.i is included directly.
+	* version.in: Removed test for definition of const.
+
+Tue Jun  1 19:23:53 2004  Stepan Kasal  <kasal@ucw.cz>
+
+	* Makefile.am (base_sources): Don't mention version.c, so that
+	it doesn't get distributed.
+	* po/POTFILES.in: Remove version.c
+	* configure.ac: Create version.i from version.in.
+	* main.c: Include version.i.
+
+Tue Jun  1 18:33:32 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Fix problem reported by Stephen Marchant <Stephen.Marchant@Cognex.com>

+	* main.c (load_procinfo): Add in version.
+
+	Unrelated: Avoid warning:
+
+	* main.c (main): Cast calls to `bindtextdomain' and `textdomain' to
+	void.  Avoids diagnostic with `configure --disable-nls'.

+	errors in comments.

+
+	Fix a bug reported by Mike Romaniw <msr@micromonumental.com>
+	to bug-gnu-utils on 2003-09-27: compl(compl(0xf0f)) returned 0xfff
+	on hosts with 64-bit uintmax_t and 64-bit IEEE-764 double, due to
+	rounding errors.
+
+	* doc/gawk.texi (Bitwise Functions): Leading nonzero bits are
+	removed in order to fit the result into a C 'double' without rounding
+	error.
+	* builtin.c: Include <float.h> if available.
+	(FLT_RADIX, FLT_MANT_DIG, DBL_MANT_DIG): Define if not already defined.

+	local variables.
+
+Mon May 31 11:49:20 2004  Stepan Kasal  <kasal@ucw.cz>

+	  different meaning there.
+
+Mon May 31 08:25:30 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (get_actual): Add extra error message for `delete f'

+
+Mon May  3 09:53:34 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* Makefile.in, */Makefile.in: Updated to automake 1.8.4.

+
+Mon May  3 09:24:45 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* configure.ac: Look for missing `strtoul'.
+	* replace.c: Include missing_d/stroul.c if not HAVE_STRTOUL.
+	* io.c (devopen): Use `strtoul' instead of `strtod' for
+	  extracting fd number from "/dev/fd/N".  (Thanks to Jim Meyering.)

+
+2004-03-18  Stepan Kasal  <kasal@ucw.cz>
+
+	* eval.c (make_scalar): Comment clarification.
+
+	* array.c (get_actual): Remove the condition ``canfatal''
+	  before ``cant_happen()''; if the data are consistent, we
+	  simply cannot get there with a non-func Node_param_list,
+	  no matter whether we are called via get_array or not.
+
+	* awkgram.y (variable): Make one longer message, to help translators.
+
+Tue Mar  9 17:34:10 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Adapted `gofast' patch from Redhat Enterprise version of grep
+	to current dfa.c.
+
+	* dfa.c (buf_offset): New variable.
+	(SKIP_REMAINS_MB_IF_INITIAL_STATE): Modified to use it, don't

+	transit_state): Use buf_offset in mblen_buf.
+	(dfaexec): Realloc things instead of free and malloc.
+
+Thu Mar  4 16:46:55 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* configure.ac (AC_FUNC_MBRTOWC): Added.

+	(REGEX_MALLOC): Removed. Not needed for new regex* routines.
+
+	* re.c (research): Removed comment and check for return of -2
+	since that was for old regex using alloca or REGEX_MALLOC.
+
+Wed Mar  3 17:10:16 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (close_one): Don't close stdout or stderr; can happen if
+	/dev/stdout or /dev/stderr are used in redirection and all the
+	open files get used.
+
+Sun Feb 29 12:17:37 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regcomp.c (build_charclass, build_charclass_op): Change type of

+
+	* awkgram.y (get_src_buf): Rewritten to better manage input and
+	supplying newlines on command line programs.  Fixes problems reading
+	source files on Cygwin.
+
+	Unrelated fixes from mary1john8@earthlink.net:
+
+	* node.c (format_val): For no malloc case, free s->stptr if necessary.
+	* io.c (nextfile): Add missing call to `unref(FILENAME_node->var_value)'
+	for no files case.
+	(close_redir): Remove file from redirection list even if fp is
+	stdout or stderr.
+
+Tue Feb 24 12:11:34 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regex_internal.c (build_wcs_upper_buffer): Enclose `offsets_needed'
+	label in `#ifdef _LIBC' to silence `unused label' compiler warning.
+
+Tue Feb 24 11:57:18 2004  Nelson H.F. Beebe  <beebe@math.utah.edu>
+
+	* regcomp.c (parse_expression): Add cast to (unsigned char *) in calls
+	to `build_charclass_op'.
+	* regex_internal.c (build_wcs_buffer): Add cast to char* in call to
+	`wcrtomb'.

+	bitset_mask, re_string_char_size_a, re_string_wchar_at,
+	re_string_elem_size_at): Change to use prototypes.
+	(re_string_char_size_at, re_string_wchar_at, re_string_elem_size_at):
+	Declare as `internal_function'.
+
+	* Makefile.am: Add rule to make .i files.  This assists in debugging.
+	* awk.h (m_tree_eval): Add casts to NULL.  (Some compilers are just
+	dumb. ADR)
+
+Mon Feb 23 15:58:39 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Clean up occupied process slots of children that have died:
+
+	* awk.h (child_catcher): New function, declare it.
+	* main.c (main): Catch SIGCHLD/SIGCLD with `child_catcher'.
+	* io.c (child_died): New static variable.
+	(child_catcher): New function, sets `child_died', reinstalls self
+	as signal handler.
+	(close_rp): New function: isolates actual fp/iop closing logic.
+	(close_redir): Call `close_rp'.
+	(get_a_record): Check `child_died' and call `wait_any(0)' if so.
+	Add descriptive comment.
+
+	Unrelated clean up:
+
+	* eval.c (fcalls): Renamed from `fcall_list'. All uses changed.
+	(pop_fcall, push_args, dump_fcall_stack): Adjusted to use indexing
+	on `fcalls' instead of a pointer into it. Avoids hassles if `fcalls'
+	is realloc-ed during recursive tree_evals. Thanks to BWK.
+
+	* config.guess, config.sub: Updated from Savannah.
+
+2004-02-19  gettextize  <bug-gnu-gettext@gnu.org>
+
+	* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.14.1.
+
+Wed Feb 18 12:40:09 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (rule): Use `msg' not `warning' for `must have an
+	an action part' message.  `warning' is wrong, since it's a real error.
+
+Mon Feb 16 12:17:39 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c, eval.c, builtin.c: Change test for `#ifdef HAVE_LOCALE_H'
+	to `#if ENABLE_NLS && defined(HAVE_LOCALE_H)' so that builds with
+	`configure --disable-nls' will actually work on non-glibc systems.
+
+Thu Feb 12 02:05:34 2004  Stepan Kasal  <kasal@ucw.cz>
+
+	Lots of misc changes from Stepan Kasal integrated.
+
+	* array.c: Various variables and parameters of static functions
+	changed from int to long, in order to prevent overflow.
+
+	* eval.c (make_scalar): New function; takes care of everything
+	that has to be done when a node of type Node_var_new or
+	Node_array_ref changes to a scalar variable.
+	(tree_eval, get_lhs): Call it.
+	(tree_eval): From now on, tree_eval(NULL) doesn't work;
+	it reports an internal error.
+	* awk.h (m_tree_eval): Likewise for the two macro versions.
+	* awkgram.y (statement): Make sure the Node_K_return's lnode is
+	always the return value, never NULL.
+
+	* Makefile.am (install-exec-hook, uninstall-links): Make use of
+	$(VERSION).
+	(INCLUDES): Renamed to AM_CPPFLAGS.
+	(AM_CPPFLAGS): The file libintl.h is generated in the

+	* awklib/Makefile.am (INCLUDES): Renamed to AM_CPPFLAGS.
+
+	* README_d/README.hpux: Change the whitespace in the appended patch,
+	so that it applies to the current source.
+	* posix/gawkmisc.c: Change a tab to a space (needed for the above).

+
+	* configure.ac: Remove obsolete versions of macros:
+	AM_INIT_AUTOMAKE doesn't need any parameters.
+	AC_OUTPUT shouldn't have any parameters either.
+	Its parameters go to a new macro: AC_CONFIG_FILES.
+	AC_CONFIG_HEADERS moved near the end of the file.
+	* configure.ac: Add [version.c:version.in] to AC_CONFIG_FILES
+	* version.in: Modify for autoconf substitutions.

+
+	* main.c (main): When checking for `close_io' failure, only set

+	* regexec.c (check_matching): Add P_MATCH_FIRST parameter.
+	(re_search_internal): Pass new parameter to check_matching.

+
+	* re.c (research): Change last param to re_search to pass

+
+	* builtin.c (sub_common): Fix logic for `&' in replacement for

+
+	* builtin.c (sub_common): Add comment and support for 2001 POSIX

+
+	* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.13.1.

+Wed Jan 14 14:26:36 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* dfa.c, dfa.h: Updated manually with most of the changes in
+	grep 2.5.1.  That version lost the ability to match newlines
+	in the data, so the merge had to be done by hand.  Sigh.
+
+2004-01-12  Paolo Bonzini  <bonzini@gnu.org>
+
+	ALLOCA patch from

+	(build_range_exp) [_LIBC]: Do not create a range
+	in MBCSET for a single-byte character set without

+	just makes the code less clear.
+	(parse_bracket_exp): Use NON_MATCH variable in
+	addition to "mbcset->non_match", not as an
+	alternative.
+	(build_charclass_op): Rename NOT parameter to
+	NON_MATCH, use it instead of declaring a variable. 
+	(parse_bracket_exp) [!_LIBC]: Pass NULL for MBCSET
+	if the character set is single-byte.
+
+Wed Jan  7 15:23:04 2004  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (mk_rexp): Set n->re_cnt to 1. Makes reinstated

+
+Tue Oct 28 18:00:00 2003  Arnold D. Robbins  <arnold@skeeve.com>

+	print name; handles varname field for -v variables, which end up
+	including the value.
+	(vname): New function.
+
+Wed Sep 24 17:32:31 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Speed up `avoid_dfa' kludge, at least a little:
+
+	* awk.h (struct Regexp): Add `has_anchor' member.  Make it and
+	`dfa' member shorts; keeps space the same.
+	* re.c (make_regexp): Set `has_anchor' member correctly.
+	(avoid_dfa): Test for `has_anchor' member instead of searching
+	for it each time.
+
+Sun Sep 21 18:34:32 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* builtin.c (state): Only needs to be 256 bytes, initstate() can't
+	use any more than that.  Well whadayaknow.
+	(do_rand, do_srand): Call `setstate' after calling `initstate'.
+
+Tue Sep 16 15:44:29 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (interpret): For Node_K_switch, add kludge_need_start stuff
+	as used in `match_op'.  Sigh.
+	* re.c (make_regexp): Add `no_dfa' variable, which is true if
+	GAWK_NO_DFA exists in the environment.  This enables run time
+	testing of things with/without the dfa matcher.
+
+Mon Sep 15 18:36:38 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	After much soul searching, reinstated old dfa code. The performance
+	of the new regex is just disastrous.  Sigh.
+
+	* awk.h (re_cnt): Reinstated old definition.
+	(struct Regexp): Added `dfareg' and `dfa' members.
+	(make_regexp): New last parameter in function, changed decl.
+	(avoid_dfa): Added declaration.
+	* awkgram.y (regexp, mk_rexp): Added use of `re_cnt'.  Fixed call
+	to `make_regexp'.
+	* Makefile.am: Add dfa.h and dfa.c.
+	* eval.c (match_op): Complexified: added call to `avoid_dfa' and
+	`kludge_need_start' variable where used to pass FALSE as last parameter
+	of research().
+	* field.c (set_FS): Fixed call to `make_regexp'.
+	* io.c (get_a_record, set_RS): Fixed calls to `make_regexp'.
+	* re.c (make_regexp): Added last paramter (`dfa') to function.
+	Complexified the code.
+	(re_update): Fixed call to `make_regexp'.
+	(research): Complexified the code, added calls to dfa stuff.
+	(dfaerror): New function.
+	(re_update): Fixed call to `make_regexp'.
+	(avoid_dfa): New function.
+
+Tue Sep  9 15:57:38 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (get_src_buf): Fix calculation of `offset' when shifting
+	source lines around.  In general, improve handling of things when
+	moving the source code line around.  What a mess this code is.
+
+Mon Sep  8 19:08:55 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (fmt_ok): Make provision for %F format and printf %'f flag
+	here too.
+
+2003-07-23  Christophe Bisiere  <bisiere@univ-tlse1.fr>  (tiny change)
+
+	* posix/regex.h (RE_TRANSLATE_TYPE): Define it to "unsigned char,"
+	  to avoid problems at hosts with signed char.
+	* posix/regexec.c (re_search_internal): Don't say
+	  "unsigned RE_TRANSLATE_TYPE."
+
+Thu Aug 28 11:09:41 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (nextfile): Change use of variable `files' to make it
+	clearer that it's a boolean flag.
+
+Tue Aug 26 22:58:15 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (useropen): Add `defined (HAVE_GETGROUPS)' as first test
+	in `#ifdef'.  Brings things in sync with same test in main.c and awk.h.
+
+Tue Aug 26 22:49:37 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* dbug.h: New file.
+
+	* array.c, awkgram.y, builtin.c, eval.c, ext.c, field.c, io.c,
+	main.c, msg.c, node.c, profile.c, re.c: Converted to use
+	Fred Fish's `dbug' library.  By default compiled out, thus
+	not affecting speed.
+
+	For the nonce, the `dbug' library itself is not shipped with
+	gawk, since I expect no-one else but me to be using it.
+
+Thu Aug 21 23:15:36 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awkgram.y (numfiles): Change extern decl to long, to match what's
+	in main.c.  Keeps things working on 64-bit systems.  Thanks to bug
+	report from Jan Oravec <jan.oravec@6com.sk>.
+
+Wed Aug 20 14:53:47 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (genflags2str): Move test for out-of-space inside test
+	for is the bit set.
+
+Mon Aug 11 11:26:51 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regcomp.c (parse_bracket_exp): If `build_charclass' fails, just pass
+	its value on as the return value.
+
+Sun Aug 10 16:59:14 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regcomp.c (build_range_exp): Make sure we don't
+	get WEOF on range characters.
+
+Tue Aug  5 21:49:32 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (get_actual): In `case Node_param_list' add test for
+	`&& (symbol->flags & FUNC) == 0' to the if.
+
+Sun Jul 13 18:28:38 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Further bug fix:
+
+	* awkgram.y (variable): Give the new variable an lnode
+	of Nnull_string if it's not an array, even if it is
+	a Node_var_new.
+
+Fri Jul 11 09:32:21 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Bug fix:
+
+	* eval.c (r_tree_eval): For Node_array_ref, set
+	tree->orig_array->var_value to Nnull_string too.
+
+	Unrelated i18n and POSIX change:
+
+	* configure.ac: Add check for local printf supporting %F format.
+	* awk.h (loc): New variable declaration.
+	* main.c (loc): Defined.
+	(main): Call `localeconv' to set loc.
+	* io.c (format_tree): Add support for printf quote flag, %'d for
+	decimal formats (not %e, %E), adds thousand separator into value.
+
+2003-07-10  Paul Eggert  <eggert@twinsun.com>
+
+	* io.c (two_way_open): If /bin/sh cannot be executed, exit
+	with status 126 consistently.
+
+Mon Jul  7 11:01:43 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* Release 3.1.3: Release tar file made.
+
+Mon Jul  7 09:55:49 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (copyleft, usage): Make sure to fflush output fp. Per Jim
+	Meyering, if error, exit non-zero.
+	* ext.c (get_argument): Fix array paramater handling.
+
+2003-07-06  Paul Eggert  <eggert@twinsun.com>
+
+	* builtin.c (do_substr): Issue better diagnostics when
+	d_substr and d_length are NaN, or when 0 < d_length < 1.
+	Be careful when comparing double to SIZE_MAX, as
+	the comparison might return the "wrong" answer when
+	`(double) SIZE_MAX' is a number that is not equal to
+	SIZE_MAX.
+	(do_gensub): Watch out for HOW values that are out of range
+	or are NaN.
+	(do_dcngettext): dcngettext wants an argument of type
+	unsigned long, not long, so use a value of that type.
+
+Fri Jul  4 10:58:02 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (main): Make option letter 'D' fall through into default
+	unknown case if not debugging. Let's us have just one version of
+	`optlist'.
+
+Thu Jun 26 15:25:57 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (get_actual): Undo Stepan Kasal change of 2003-06-17.
+	See test/match2.awk.
+
+Wed Jun 25 15:26:08 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* builtin.c (do_rand): Change calculation so that result
+	obeys constraint:  0 <= N < 1.  This is per history and POSIX.
+	Thanks to Nelson Beebe (beebe@math.utah.edu) for reporting
+	this issue.
+
+Mon Jun 23 15:13:39 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (rs1scan): Per advice from Bruno Haible, it's safe
+	to skip the multibyte checking code if RS is '\n'. See
+	the comment in the code.  Big performance improvement for
+	multibyte locales.
+
+2003-06-20  Stepan Kasal  <kasal@ucw.cz>
+
+	* eval.c (comp_func): If memcmp returns 0, we have to compare
+	  the lengths.
+
+2003-06-19  Stepan Kasal  <kasal@ucw.cz>
+
+	* eval.c (interpret) <Node_K_arrayfor>: Use NULL, not 0, to
+	  initialize the variable list.
+	  (comp_func): Array indices no longer are string values,
+	  you have to use ahname_str, ahname_len.
+
+Tue Jun 17 11:53:46 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (get_actual): Make check for isparam
+	smarter: also check for FUNC flag.
+
+2003-06-17  Stepan Kasal  <kasal@ucw.cz>
+
+	* array.c (get_actual): Even if canfatal is FALSE, don't
+	  tolerate existence of things which can't happen.
+
+Mon Jun 16 16:21:44 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* configure.ac: Removed m4/Makefile.
+	* m4/Makefile.am: Removed.
+
+2003-06-16  gettextize  <bug-gnu-gettext@gnu.org>
+
+	* configure.ac (AC_OUTPUT): Add m4/Makefile.
+	(AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
+
+Sun Jun 15 20:45:43 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (get_a_record): Enhance logic to fill buffers to include
+	`|| no_data_left(iop)'.
+	(rs1scan): Fix logic for setting recm fields for multibyte
+	character case.
+
+2003-06-10  Stepan Kasal  <kasal@ucw.cz>
+
+	* awkgram.y (release_all_vars): Do not try to release a value of
+	  Node_var_new; after get_lhs, use the lhs directly, do not try
+	  to do (*lhs)->var_value; the Node_var case doesn't need
+	  special treatment.
+	* builtin.c (do_match): `get_param' is successful iff it returns
+	  Node_var_array---if the variable was new, get_param has already
+	  changed the type.
+	* field.c (do_split): Likewise.
+
+Sun Jun 15 19:36:35 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* node.c (r_dupnode): Typo fix in hash tables: stptr -> ahname_str.
+	Thanks to mary1john8@earthlink.net.
+	* array.c (get_actual): Add `if (canfatal)' before call to
+	`cant_happen'.
+
+Sun Jun 15 19:25:49 2003  Patrick T.J. McPhee   <ptjm@interlog.com>
+
+	* awk.h (memcpy_ulong): Add ! WIN32 to ifdefs.
+
+Mon Jun  9 18:38:20 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* custom.h (hpux): Added stuff to (hopefully) get `tzset'
+	declared on HP/UX 10 and up.
+
+Mon Jun  9 17:12:24 2003  Patrick T.J. McPhee   <ptjm@interlog.com>
+
+	* awk.h (ATTRIBUTE_EXPORTED): New macro for dynamic libs on Windows32.
+	* CONVMFTidx, stack_ptr, do_lint, lintfunc: Now have this attribute.
+
+Mon Jun  9 13:11:33 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Clean up of Stepan's patches.
+
+	* array.c (get_actual): Renamed from r_get_array. Added second
+	param canfatal if routine should print fatal message when not an array.
+	(get_actual): Renamed 'prm' to `isparam'.
+	(array_vname): Add static msglen var; only realloc string if it grows.
+	Don't use `s += sprintf(...)'. No good on old systems where sprintf
+	returns char *.  Minor formatting cleanups.
+	(do_adump): Restored separate `a' and `r' variables; helps for debugging.
+
+	* awk.h (SCALAR, UNINITIALIZED): Removed entirely, renumbered other flags.
+	(get_array, get_param): New macros, calls get_actual.
+	(get_actual): Declaration changed from that of r_get_array.
+
+	* awkgram.y (release_all_vars): Restored previous version of code; new
+	version isn't right for Node_xx variables.
+	(variable): Minor code cleanup for readability.
+
+	* builtin.c (do_match): Use get_param and print our own message when
+	third parameter is not an array.
+
+	* eval.c: Added a few comments here and there, removed some no longer
+	needed comments.
+
+	* field.c (do_split): Use get_param and print our own message when
+	second parameter is not an array.
+
+Mon Jun  9 11:46:21 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (do_delete): Initialize hash1 and last to keep gcc -Wall happy.
+	* io.c (rsnullscan): Comment out label skip_leading for same reason.
+
+Wed May 28 08:31:23 CEST 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* eval.c (forloops_active, in_function): Nuked.
+	(pop_all_forloops, pop_fcall_stack): Are now inline.
+
+Wed May 28 07:58:35 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* field.c, awk.h (Null_field): No longer static.
+	* field.c (init_fields): Initial value of $0 can be Nnull_string,
+	  no need to copy it.
+	* eval.c (r_get_lhs) <Node_field_spec>: Test for uninitialized field,
+	  which is Nnull_string for $0 and Null_field for $(>0).
+	* builtin.c (do_print_rec): Test for uninitialized $0.
+
+Tue May 27 17:03:02 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* awk.h (Node_var_new): New node type for variables which can be
+	either scalar or array.  From now on, Node_var is always scalar.
+	(Node_gvar_ref): Nuked, its role can be taken by Node_array_ref.
+	(orig_var): Removed, orig_array is enough.
+	(SCALAR, UNINITIALIZED): Flags nuked.
+	(var_uninitialized): New macro to distinguish uninitialized vars;
+	used in several other macros.
+	* array.c (r_get_array, array_vname, do_adump): Adapt to the
+	above changes.
+	* awkgram.y, eval.c, field.c, main.c, node.c, profile.c: Ditto.
+
+Tue May 27 14:27:50 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* array.c (r_get_array): New function, which goes all the way
+	through Node_param_list to actual Node_var_array; if it encounters
+	non scalar Node_var, it changes it to Node_var_array.
+	(in_array, do_delete, do_delete_loop, do_adump, assoc_sort_inplace):
+		Use get_array.
+	(assoc_lookup): The parameter must be a Node_var_array.
+	* awk.h (get_array, r_get_array): Declare the new function and define
+	a macro to speed it up.
+	* builtin.c (do_match): Use get_array.
+	* eval.c (interpret) <Node_K_arrayfor>: Ditto.
+	(r_get_lhs) <Node_K_arrayfor>: Ditto.
+	* field.c (do_split): Ditto.
+
+Tue May 27 08:23:51 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	Changed node->vname meaning for type Node_array_ref and Node_gvar_ref.
+	It contains only the reference name; one has to (recursively) follow
+	node->prev_array to find out the call history for the array.
+
+	* array.c (array_vname): New function to print the array name.
+	(assoc_lookup, do_delete): Use array_vname.
+	* eval.c (interpret, r_tree_eval, r_get_lhs): Use array_vname.
+	(push_args, pop_fcall): Things have simplified.
+	* awk.h (array_vname): Declare.
+	(prev_array): Define.
+
+Sun Jun  8 11:25:36 2003  Stepan Kasal  <kasal@ucw.cz>
+
+	* awkgram.y (append_right): When using savetail, remember that it
+	is not necessarily the tail of the list---it's just a pointer to
+	the last chunk appended.
+
+Thu Jun  5 12:01:41 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* builtin.c (do_strtonum): Make `strtonum(13)' work.
+
+Wed Jun  4 17:07:06 2003  Corinna Vinschen  <vinschen@redhat.com>
+
+	* io.c (binmode): Include function for __CYGWIN__ too.
+
+Tue Jun  3 12:40:50 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (interpret): Node_K_switch.  For regex case, don't
+	call `free_temp' on the result of `force_string' if it's equal to
+	switch_value. Thanks to John DuBois <spcecdt@armory.com>
+	for finding the problem.
+
+Sun Jun  1 13:08:22 2003  Arnold D. Robbins  <arnold@skeeve.com>
+

+
+	* awkgram.y (isnoeffect, isassignable): Add Node_TEXTDOMAIN to
+	switches in both functions.
+
+Wed May 28 11:38:59 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* awkgram.y (switch_body): Remove rule ``switch_body:/*empty/''
+	as ``switch_body:case_statements'' covers it---this disambiguation
+	fixes a reduce/reduce conflict.
+
+Sun May 25 16:23:43 2003  Corinna Vinschen  <vinschen@redhat.com>
+
+	* configure.ac: Remove linking against /usr/lib/automode.o.
+	* configure: Regenerate.
+
+Sun May 25 15:19:19 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* awk.h (get_lhs): For an initialized Node_var, you may return
+	the address of var_value pointer, no matter whether reference
+	bit was set or not.  We were silly slowing down most of the
+	assignements.
+
+	* (get_a_record): After grow_iop_buffer, move recm.rt_start even
+	if recm.len == 0.
+
+Mon May 19 16:55:59 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Code for C-style switch statements. Initial version contributed by
+	Michael Benzinger <Michael.Benzinger@sabre-holdings.com>.
+
+	Disabled by default, use `configure --enable-switch' to turn it on.
+
+	* configure.ac: New AC_ARG_ENABLE for switch statements.
+	* awk.h (NODETYPE): New types for switch, case, default keywords
+	and respective lists.

+	avoid duplicate cases.
+	* eval.c (nodetypes): New entries for new NODETYPEs.
+	(interpret): New code to do switch execution.
+	* profile.c (pprint): New code to print switch statements.
+
+Mon May 19 15:05:43 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* configure.ac: Renamed from configure.in.
+	* fixvers: Now looks in configure.ac.
+	* Makefile.am: Now cites configure.ac.
+

+
+Wed May 14 09:01:16 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	Misc patches:
+
+	* builtin.c (do_match): If third parameter to `match' is supplied,
+	store all subexpressions which are applicable, even though there
+	are some unused between them.
+
+	* awkgram.y (yylex): When returning from unterminated REGEXP
+	(which is /* kludge */), take care to fake a yylval, to
+	prevent ``internal error'' later.
+
+Sun May 11 15:51:00 2003  Stepan Kasal  <kasal@math.cas.cz>
+
+	* io.c (rsnullscan, get_a_record): Boundary condition bug fixes.
+
+Sun May 11 15:15:20 2003  Scott Deifik  <scottd@amgen.com>
+
+	* awk.h: Add decls for `memcpy_ulong', `memset_ulong', and
+	MSC defines.
+	* regex.c: Include <stdio.h> if MSC for size_t.
+
+Mon May  5 15:11:06 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (get_a_record): Only tweak RT's value in place if the current
+	RS scanner is the same as the last one. Bug report submitted by
+	John DuBois (<spcecdt@armory.com>).
+
+Fri May  2 14:39:48 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (get_a_record): Add logic at end to be smart about setting
+	RT.  Saves considerable time, esp for default case where RS = "\n".
+
+Wed Apr 30 11:44:38 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* field.c (do_split): Add check and code for Node_gvar_ref.
+	* array.c (in_array, do_delete, asort_actual): Same.
+	* builtin.c (do_split): Same for 3rd arg array parameter.
+	* eval.c (interpret): Same for Node_K_array_for.
+	(push_args): Same for evaluating extra args.
+
+Tue Apr 29 15:54:28 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Record reading code redone/simplified considerably.
+
+	* awk.h (IOBUF): Removed total field, no longer used.
+	* io.c (at_eof, has_data, no_data_left): New macros.
+	(RECVALUE, SCANSTATE): New enumerated types.
+	(rs1get_a_record, rsnull_get_a_record, rsre_get_a_record): Removed.
+	(get_a_record): Rewritten, again. Now contains just buffer and
+	record code; searching code moved into these functions:
+	(rs1scan, rsnullscan, rsrescan): New functions to scan a buffer
+	for record contents and terminator. Fill in values in:
+	(struct recmatch): Holds found record and terminator.
+	(spec_setup): Set iop->dataend to indicate data is already in buffer.
+	(nextfile, inrec): Use new macros instead of flag and pointer tests.
+	(set_RS): Set scanning function instead of record function.
+
+	FWIW, it all passes `make test'.
+
+Sun Apr 27 21:02:39 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (do_close): At end, if do_posix return 0. See comment in code.

+	* configure.in: Check existence of wcrtomb, and wcscoll.
+	* configh.in: Likewise.
+	* configure: Re-generate.
+	Thanks to Kimura Koichi <kimura.koichi@canon.co.jp> for reporting.
+
+Sun Apr 13 16:02:10 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (main): Add call to `setlocale' for LC_NUMERIC after program is
+	parsed.
+	(arg_assign): Switch back to "C" locale for LC_NUMERIC for command
+	line assignments; this is per POSIX that period is decimal point for
+	program and command line assignments and the locale's separator
+	applies for input, output, and string to number conversion.
+
+2003-03-26  Paul Eggert  <eggert@twinsun.com>
+
+	* builtin.c [HAVE_INTTYPES_H]: Include <inttypes.h>.

+	(TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): New macros, taken from
+	coreutils and many other GNU utilities.
+	(format_tree): When formatting, use widest possible integers
+	rather than settling with 'long'.
+	(do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Likewise,
+	when doing bitwise operations.
+	* configure.in (jm_AC_TYPE_LONG_LONG, jm_AC_TYPE_UNSIGNED_LONG_LONG,
+	jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Add, since the mainline
+	code now needs this.
+	* doc/gawk.texi (Control Letters, Bitwise Functions): Document this.
+	* m4/intmax_t.m4: New file, taken from coreutils (but renamed to
+	avoid collision with our m4/inttypes.m4).
+	* m4/longlong.m4: New file, taken from coreutils.
+	* m4/uintmax_t.m4, m4/ulonglong.m4: Remove; superseded by the above
+	new m4 files.
+
+	* builtin.c (BITS_PER_BYTE): Remove; use CHAR_BIT instead, since
+	it's the standard name.
+	(do_lshift, do_rshift): Complain if the shift width is exactly equal

+
+Thu Mar 27 10:44:11 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
+	Enhance check for no data left in file to be only if file has

+
+Wed Mar 19 13:45:50 2003  Corinna Vinschen  <vinschen@redhat.com>
+
+	* regex.c [RE_ENBABLE_I18N]: Remove definition; the one in
+	regex_internal.h is better and makes things work with Cygwin.
+
+Tue Mar 11 11:54:20 2003  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regex_internal.h: Don't include <limits.h> after <regex.h> was
+	included in regex.c, since it could redefine RE_DUP_MAX to a lower
+	value.
+	(bitset_set, bitset_clear, bitset_contain): Use 1UL instead of 1 in
+	left shift operations.
+	* regex.c: Include <limits.h> before <regex.h>
+	* regcomp.c (re_compile_fastmap_iter, init_word_char, parse_expression):
+	Use 1UL instead of 1 in left shift operations.
+
+Mon Mar 10 15:45:37 2003  Corinna Vinschen  <vinschen@redhat.com>

+	  expression_value is now treated similarily as begin_block and end_block.
+	  (pattern, rule): Bison actions for non-terminal `pattern' now
+	  add a new rule to the appropriate Node_rule_list, action for
+	  non-terminal `rule' now only adds the associated code block

+
+	* builtin.c (do_substr): Consistently use floating point

+
+Mon Oct 28 16:35:39 2002  Arnold D. Robbins   <arnold@skeeve.com>
+

+	(array_init): Change hash function based on environment for
+	experimentation.
+
+Mon Oct 28 13:21:20 2002  Arnold D. Robbins   <arnold@skeeve.com>
+
+	Applied lots of patches from Stepan Kasal, tweaked as needed
+	for current code base.
+
+	* node.c (dupnode): When n->stref overfows, flag the node as PERM.
+	Same for n->ahname_ref.
+	(unref): Remove the check for n->stref == LONG_MAX and
+	n->ahname_ref == LONG_MAX.
+	* awk.h (make_string): The third argument to make_str_node changed
+	from FALSE to 0, it's not Boolean.
+	(free_temp): Evaluate the argument only once, so that we
+	can call free_temp(tree_eval(n)) for achieving side effects.
+	(load_environ, load_procinfo): Changed return type to NODE *.
+	* main.c (load_environ): The ENVIRON_node should be created with type
+	Node_var_array and lnode set to NULL.  Return pointer to the created node
+	and create an empty hash even on TANDEM.
+	(load_procinfo): Same mods for PROCINFO_node.
+	(init_args): ARGV_node should also have lnode set to NULL.
+	* eval.c (r_tree_eval): case Node_assign moved just above the other
+	assignment cases.
+	(op_assign): ++ and -- cases merged with += and -=, respectively.
+	(push_args): Evaluate all args, even in cases where more args are
+	supplied then required.
+	(interpret): In case Node_K_forarray, flag the variable
+	num_elems also as volatile, so that it survives longjmp() and
+	can be trusted when linting code.
+	(r_get_lhs): Case Node_param_list was unreachable (unless
+	something breaks really badly), remove it;
+	(r_tree_eval): Case Node_var_array removed from the last switch,
+	it was caught in the first switch above.
+	* profile.c (tree_eval): Again, case Node_var_array was caught above.
+	* awkgram.y (variable): Code simplified, making use of the above
+	changes.
+	* field.c (sc_parse_field): IGNORECASE only applies to regex based
+	field-splitting, so remove code that pays attention to it.
+	(do_split): Don't use parse_field if RS_is_null.
+	(set_FS): Beware of FS == "\\" even if RS_is_null.
+
+	Code changes to make things work better:
+	* field.c (set_FS): Don't use cmp_nodes() to compare old and new
+	value of FS, that uses IGNORECASE, which is a bad idea. Improve
+	logic for choosing sc_parse_field.  Ensure that when RS_is_null
+	but using a single character, that we do pay attention to
+	case when doing regex splitting.
+	* io.c (set_RS): Don't use cmp_nodes() to compare old and new
+	value of RS, that uses IGNORECASE, which is a bad idea.
+
+Mon Oct 28 09:43:14 2002  Arnold D. Robbins   <arnold@skeeve.com>
+
+	* recomp.c (parse_expression): Change return statement into
+	two so it'll compile for SGI cc.
+
+	* awk.h (STR, CUR): Changed to STRCUR and NUMCUR respectively,
+	to avoid conflict with STR on some System V systems.  Changed
+	in all source files.
+
+Thu Oct 24 16:14:34 2002  Arnold D. Robbins   <arnold@skeeve.com>
+
+	* array.c (AVG_CHAIN_MAX): Now a variable, to allow easy experimentation.
+	(array_init): Pulls a new value from env var AVG_CHAIN_MAX if it
+	exists and sets the variable.
+	* awk.h: Add declaration for array_init().
+	* main.c (main): Call array_init().

+

+	(duplicate_node): Remove the handling OP_CONTEXT_NODE.
+	(calc_inveclosure): Likewise.
+	(calc_eclosure): Likewise.
+	(calc_eclosure_iter): Invoke duplicate_node_closure instead of

+	warning.

+	(pop_fail_stack): Fix the memory leak.
+	(set_regs): Likewise.

+	OP_CONTEXT_NODE.
+	(update_cur_sifted_state): Append some if clause to avoid redundant
+	call.
+	(sub_epsilon_src_nodes): Use IS_EPSILON_NODE since it might be a
+	back reference.
+	(check_dst_limits): Remove the handling OP_CONTEXT_NODE.

+
+Tue Oct 15 14:18:53 2002  Arnold D. Robbins   <arnold@skeeve.com>
+
+	* eval.c (set_IGNORECASE): Call set_RS() instead of
+	set_FS_if_not_FIELDWIDTHS().  The former calls the latter
+	for us, and also makes IGNORECASE affect RS like it's supposed to.
+	* field.c (FS_re_yes_case, FS_re_no_case): New variables.
+	(set_FS): Smarten up routine to not recompile FS_regexp if all
+	that's changed is IGNORECASE or if switching back to FS from
+	FIELDWIDTHS.  Significant speed-up for cases where IGNORECASE
+	is assigned to for every record.
+	* io.c (RS_re_yes_case, RS_re_no_case): New variables.
+	(set_RS): Similar changes as to set_FS().  In particular,
+	IGNORECASE changing now affects record splitting too.
+	* re.c (refree): Set rp->pat.tranaslate to NULL. It comes
+	from casetable and shouldn't be freed. (Strictly necessary
+	only for old regex, but a good idea anyway).
+	Also, call regfree(& rp->pat) instead of manually free()ing
+	things, since there's dynamically allocated stuff hiding in
+	the buffer. Avoids a memory leak.
+
+Mon Oct 14 12:02:39 2002  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Major space reduction in array management.  Overhead reduced
+	to two NODE's per element from three.

+	(ahname_str): New member, points into hash union.
+	(ahname_len): New member, points into hash union.
+	(ahname_ref): New member, points into hash union.
+	* array.c: Replaces uses of ahname member with string and
+	length.  Set the reference count correctly to 1 on new nodes.
+	* eval.c (interpret): Case for Node_K_arrayfor.  dupnode() the
+	array indices, and set loop variable to new value made via
+	make_string().
+	* node.c (unref, dupnode): Node_ahash nodes are now also
+	reference counted, a la strings.  Similar code is used to
+	increment/decrement the counts, and/or copy nodes as
+	needed.
+
+	Unrelated:
+	* awk.h (forsub): Removed. Not used.
+
+Sun Oct 13 16:58:27 2002  Stepan Kasal  <kasal@math.cas.cz>
+
+	* profile.c (pprint): #undef the temporary defines at the end
+	of the case.
+	* eval.c (interpret): Likewise.

+	* field.c (set_NF): ... to here.
+	* main.c (varinit): No need to call set_NF().
+	* awkgram.y (statements): Don't be so generous when concatenating
+	`statements' with a `statement'.
+

+	with a comment that it's internally the same as `delete array'.
+	* eval.c (Node_K_delete_loop): Increment the exec_count. Ooops.

+	macro.

+
+	* awkgram.y (getfname): Return NULL if not found, remove
+	fatal error.  Could be an extension function.
+	(dump_funcs): Walk symbol table counting functions before
+	mallocing table, since there could be extension functions,
+	func_count could be too small.
+	* profile.c (pp_builtin): Handle NULL return from getfname().
+	Print it as "extension_function()" if so.

+
+Wed Nov 14 16:12:40 2001  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* builtin.c (bchunk_one): Use `ofre < 1' instead of `ofre <= 0'

+
+2001-09-07  Paul Eggert  <eggert@twinsun.com>
+
+	* io.c (redirect): When deciding to use the fdopen bug hack,
+	  use "__sun" rather than "solaris".  No compilers predefine
+	  "solaris", but both GCC and Sun C predefine "__sun".
+
+Thu Aug 30 15:17:12 2001  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (copyleft): Use a printf %d for last year of update

+
+2001-08-13  Paul Eggert  <eggert@twinsun.com>
+
+	This patch fixes a bug that causes gawk to rewind standard
+	input incorrectly.  It also removes all instances of fseek,
+	from the gawk source proper, which should make gawk a bit
+	more portable.
+
+	(The original patch removed off_t & lseek too, but I need
+	that for something else. ADR.)
+
+	* posix/gawkmisc.c (optimal_bufsize):
+	Don't use lseek on the input, because that might change
+	its state.  Instead, just check whether it is a regular file.
+	This obviates the need to invoke isatty.

+	* pc/gawkmisc.pc, unsupported/atari/gawkmisc.atr: Likewise.

+	  to protect against FS[1] = "x" kinds of things.  It'd be better

+	  effective.
+
+	Undid BECAMEARRAY changes of 25 June 2001 in favor of correct code:
+	* eval.c (pop_fcall): Change test and comment for freeing n->vname.
+	  (flags2str): Removed BECAMEARRAY entry.
+	* awk.h (BECAMEARRAY): Removed define.

+
+	* io.c (get_a_record): Handle case where RS = "" and input file
+	  is only newlines.  See test/onlynl.   Bug report by

+
+	* profile.c: Move enum for redirection placement to top

+
+	* array.c (assoc_lookup): Fix call to fatal to lintwarn instead.
+	* node.c (r_force_number): Use `0 &&' to disable warnings about
+	  conversions: they're overzealous, methinks.
+
+Thu Apr  8 14:27:58 1999  Arnold D. Robbins  <arnold@skeeve.com>

+
+	* configure.in: Add BeOS to list of cases where we hardwire
+	  GETPGRP_VOID.

+
+Mon Nov 30 20:52:52 1998  Arnold D. Robbins  <arnold@skeeve.com>
+

+
+	* eval.c (r_get_lhs): case Node_field_spec.  Fix the lint
+	  warnings for field reference of null string or non-numeric value.

+
+Thu Nov  5 16:58:38 1998 Arnold D. Robbins  <arnold@skeeve.com>
+

+
+	* builtin.c (do_*): Added lint checks for non-numeric
+	  and/or non-string arguments, as appropriate. This should

+	* awk.h (reisstring): New prototype.

+	  a simple string match. This is rather simplistic in its logic.
+	* io.c (get_a_record): In the case that RS is a regexp, AND
+	  the re matched at the exact end of the buffer, add a call to
+	  `reisstring' in case it's a simple string match. If so, we
+	  don't need to read more into the buffer because we don't
+	  have a regex like `x.*y' that might extend longer.
+	  This should be very helpful for interactive /inet clients
+	  where something like `RS = "\r\n"' happens.
+
+Thu Aug 13 22:07:40 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (socketopen): Fixes from Juergen Kahrs to socket

+
+	* io.c (devopen): Relax previous change, don't require "any",

+
+	* node.c (parse_escape): Add warning that is always on

+	  builtin variables. Gotta look nice, don't we?
+	* eval.c (nodetypes): Ditto.
+	  (genflags2str): Added code to check that we don't
+	  overflow the static buffer. This is just a debugging
+	  routine, not worth the hassle of dynamic allocation.
+
+Mon Mar  2 16:06:16 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* Makefile.in (dist): Remove any embedded copied RCS or CVS

+
+	* builtin.c (format_tree): Workaround a DEC C V5.7 bug by

+
+Sun Feb  6 11:39:33 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (op_assign):  Fix it right.  For ++ and --, get the lhs

+
+	* node.c (parse_escape): Add lint warning for unrecognized

+
+	* builtin.c (do_compl): Test `d' for negative inside the do_lint

+
+	* awk.h (nextc): Remove declaration, don't need it here.
+	  awk.y (nextc): Cast values to unsigned char so that latin-1
+	  characters in strings don't turn themselves into EOF.
+	  Most notably y-umlaut, which is decimal 255.
+
+Mon Nov  1 20:00:25 1999  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* regex.c (init_syntax_once): Move below definition of

+	  (SYNTAX): And subscript with 0xFF for Latin-1 characters.
+
+Mon Oct 25 18:37:13 1999  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h, main.c, io.c: Undo previous changes (22 Oct 1999).
+	* main.c (main): Move call to `init_fields()' to before
+	  arg parsing.  This allows `-v NF=blah' to work ok.
+
+Fri Oct 22 17:43:40 1999  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (arg_assign): Add new arg, `initing' for icky special

+
+	* array.c (assoc_lookup): Removed code that gave each array
+	  a private copy of each index.  Balloons memory usage for
+	  no good reason that I can see.  Just use dupnode in all
+	  cases.
+	* configure.in: Check for $srcdir/.developing adds extra
+	  defines for my testing/debugging use.  Yes, hack alert.
+

+	* awk.y, builtin.c, eval.c, field.c, io.c: Removed include

+
+	* io.c (iop_alloc): Don't mmap files whose sizes don't fit in `int'.
+	  [ This isn't really needed, as HAVE_MMAP is #undef'ed at the top,
+	  but it's there in case people want to take their life in their hands. ]

+
+Wed May 19 14:02:54 1999  Arnold D. Robbins  <arnold@gnu.org>
+
+	* io.c (do_close): Move test for `close(FILENAME)' to after

+	* configure.in: Call it

+

+
+Sun May  2 18:25:43 1999  Arnold D. Robbins  <arnold@gnu.org>
+

+	  from the front of records when RS = "" and there's only one
+	  newline at the front of the file, which the regex didn't catch.
+
+Wed Apr 28 12:27:49 1999  Arnold D. Robbins  <arnold@gnu.org>
+
+	* configure.in: More HP stuff: fix the manual alloca code so that

+
+Tue Nov  3 16:24:35 1998  Arnold D. Robbins  <arnold@gnu.org>
+
+	* eval.c (r_get_lhs): Fix the cases for the special variables,
+	  don't unref their current value if it's the same as the internal
+	  copy; perhaps the current one is used in a concatenation or some
+	  other expression somewhere higher up in the call chain.  Ouch.
+	  See test/getnr2tm.awk.

+
+	* builtin.c (format_tree): Improve handling of zero-fill

+
+	* eval.c (r_tree_eval): Case for Node_concat. Get lengths
+	  separately, in case one expression has a side effect that
+	  that changes another. Ugly, but it keeps gawk from core
+	  dumping. See test/nasty.awk.
+
+Sun Oct 18 21:27:24 1998  Arnold D. Robbins  <arnold@gnu.org>
+
+	* awk.y (append_right): Bug fix, if `list' or `new' are NULL,

+
+Mon Mar 23 21:22:32 1998  Arnold D. Robbins  <arnold@gnu.org>
+
+	* eval.c (r_get_lhs): Make sure that values of type
+	  Node_param_list don't have the FUNC flag set. This means
+	  we don't allow the use of a function name as a variable or
+	  array from within the function.
+
+Sun Mar 22 19:12:32 1998  Paul Eggert  <eggert@twinsun.com>

+
+	* field.c (using_FIELDWIDTHS): New macro.
+	  (using_fieldwidths): Use new macro.
+	  (do_split): In case for FS_DFLT, also check that
+	  we're not using FIELDWIDTHS. Otherwise, split() would use
+	  FIELDWIDTHS, not current value of FS. Oops.
+
+Sun Nov 16 20:08:59 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* builtin.c (sub_common): Fix for count of matches in gsub

+
+Wed Oct 15 03:38:12 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* field.c (set_FS): Use `sc_parsefield' if the value of FS is not
+	  alphabetic OR if not ignoring case. Bug fix if IGNORECASE

+	  fields. Thanks to Alan J. Broder (ajb@dtmr.com).
+
+Sun Oct  5 11:56:52 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* configure.in: If ISC add -D_SYSV3 to CFLAGS, per email from

+
+Wed Sep 17 15:34:15 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* field.c (rebuild_record): Set things up so that all fields point
+	  into the new record and release any changed fields without
+	  causing memory leaks.  Avoids problems when fields are extended
+	  with the value of $0 or other fields and then $0 is assigned to.
+
+Mon Sep 15 16:12:55 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* builtin.c (do_print): When testing for NUMBER, make sure
+	  it's not a string too. Thanks to Michael Brennan for
+	  clarifying the semantics.
+
+Sun Sep 14 19:55:12 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* node.c (format_val): Always format values ourselves: avoids
+	  problems if OFMT is bizarre, like %s.
+
+Sun Sep 14 00:08:53 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* io.c (get_a_record): Replace all occurrences of the test
+	  `grRS == FALSE' with `RS_is_null' which makes ` RS = "\0" '
+	  actually work, is clearer code, and actually makes use of
+	  the `RS_is_null' variable!
+
+Sun Aug 17 07:15:12 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* field.c (set_FS): Change logic to always set parse_field, even
+	  if FS hasn't changed. Thanks to Igor Sheyn for catching this.
+
+Wed Aug  6 21:04:37 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* io.c (VMS et al gawk_popen): Use pclose, not fclose, if
+	  iop_alloc fails.
+
+Wed Jul 30 19:53:52 1997  Arnold D. Robbins  <arnold@gnu.org>

+
+	* awk.y (get_src_buf): Don't close file if it's stdin.

+
+Thu Jul 17 20:05:59 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* builtin.c (do_print): When OFMT != CONVFMT, create a new
+	  temporary node with just the numeric value valid and format it,
+	  and use that for printing. Avoids memory corruption.
+
+Wed Jul 16 10:01:16 1997  Arnold D. Robbins  <arnold@gnu.org>
+
+	* regex.c: When SYNTAX_TABLE is defined, but not emacs, then
+	  CHAR_SET_SIZE is not defined, though used in regcomp.  It should
+	  be taken out of #ifdef SYNTAX_TABLE. Fix from bug group, from
+	  Akim Demaille, demaille@inf.enst.fr.
+	* awk.h (isnondecimal): Make test a little smarter.
+	* builtin.c (nondec2awknum): Add bailout for decimal numbers, e.g.

+
+	* eval.c (interpret): case Node_K_next, Node_K_nextfile: fatal
+	  error if called from BEGIN or END.

+
+	* builtin.c (nondec2awknum): Allow `f' and `F' in hexadecimal numbers.

+	* random.c, builtin.c: Remove __GLIBC__ tests, since it breaks
+	  `make test'. I prefer consistency across platforms.
+	* Makefile.in (gawk): Undid April 25 changes and added comment.
+	  Putting COMPLAGS in breaks with -g on VMS POSIX.
+
+Sun May 11 14:48:04 1997  Darrell Hankerson  <hankedr@mail.auburn.edu>
+
+	* io.c [MSC_VER]: Add cases for WIN32.
+	* regex.c [MSC_VER]: Add cases for WIN32.
+
+Sun May 11 07:04:01 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_print): In the loop that evaluates each expression
+	  to be printed, do a dupnode to avoid bizarre output. Thanks to
+	  Michal for finding this problem.
+	* awk.y (yylex): Fix scanning of hexadecimal constants.
+
+Wed May  7 15:09:25 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

+
+Mon May  5 06:33:47 1997  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* io.c (nextfile): Move the check for null return from iop_open
+	  in the normal case and add one for the "no args" case.
+
+Fri Apr 25 16:52:33 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* array.c (grow_table): Add a bunch more large primes so arrays

+	* all files: Remove ifdef'ed out code and update copyrights.
+	* Makefile.in (gawk): Add $(COMPFLAGS) to command line.

+
+	* COPYING: Changed to current official version from FSF.
+	* regex.c: Merge with GLIBC version.
+	* awk.h [_GNU_SOURCE]: Bracket definition inside ifdef.
+	  (NODE.source_line): Move name member out of `x' union and
+	  into `nodep'; avoids problems doing diagnostics.
+	  (nondec2num): Put decl into #if BITOPS || NONDECDATA
+	* posix/gawkmisc.c, missing/system.c, missing/strtod.c,
+	  missing/strerror.c: Move to generic GPL statement at top.

+
+Tue Apr 15 21:35:45 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!

+
+	* Makefile.in [COMPFLAGS]: Per suggestion from Karl Berry, put
+	  $(CFLAGS) last.
+
+Tue Apr  8 23:54:46 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (interpret): For Node_K_break and Node_K_continue, if
+	  treating them like `next', also check the function call stack
+	  and pop it if necessary.
+
+Mon Apr  7 18:22:37 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+

+
+	* io.c (iop_alloc, iop_close): Undo changes of Feb 11, apparently
+	  other cleanups in io.c made mmap stuff start working again.
+	  BAH! It's a mess, the test suite still fails. I'm leaving the
+	  mmap stuff undefined for now. It'll probably get ripped out in 3.1.
+
+Thu Mar 27 08:48:57 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* custom.h [_SEQUENT_]: Undef HAVE_MMAP.

+
+Mon Mar 24 23:09:07 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* field.c (init_fields, etc..): More clean up use of Null_field
+	  and the various flags.
+	* node.c (unref): If a field, free the node itself. Fixes
+	  memory leak problems.
+
+Sun Mar 23 22:51:09 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.h [FIELD]: New flag for node->flags field.
+	* builtin.c (sub_common): If FIELD is set, dup the string.
+	* field.c (init_fields): Set up a new Null_field global var.
+	  (init_fields, set_field, set_record) use the FIELD flag.
+	  (getfield): Use Null_field instead of private variable.
+	* io.c (wait_any): Comment out calls to pclose and iop_close,
+	  caused weird race conditions. See test/pipeio1.awk. Thanks
+	  to Darrell Hankerson for tracing this one down.
+
+Tue Mar 18 20:57:18 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* dfa.c (inboth): Free templist; plugs memory leak.
+	* field.c (init_fields, grow_fields_arr, set_field, rebuild_record,
+	  set_record): Remove PERM flag from entries in fields_arr[]. Fixes
+	  nasty memory leak.
+
+Tue Mar 18 06:33:00 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.y (dup_parms): Robustified against parameter errors.
+
+Sun Mar 16 21:31:40 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
+	* acconfig.h [BITOPS]: New macro. If set, do octal & hex and bit ops.
+	* awk.h [isnondecimal]: New macro, and decl of new functions.
+	* awk.y (yylex): Add recognition of octal and hex constants.
+	* builtin.c (do_and, do_or, do_xor, do_lshift, do_rshift): New
+	  functions that do bit operations.
+	  (nondec2awknum): New function to convert octal or hex to double.
+	* configure.in: Add AC_ARG_ENABLE for bit operations.
+	* node.c (r_force_number): Add octal and hex conversion.
+
+Sun Mar 16 21:28:56 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.h [IOP_NOFREE_OBJ]: New macro.
+	* io.c (iop_open, iop_alloc): Add new third parameter, which is
+	  either NULL, meaning allocate a new IOP, or the address of one
+	  already allocated.  Have a static one in the `nextfile'
+	  routine, and use the IOP_NOFREE_OBJ flag for it.  All of this
+	  keeps us from reading freed memory. The `swaplns' test fails
+	  otherwise.
+	  (iop_close): If IOP_NOFREE_OBJ is set, don't free the IOBUF.
+
+Wed Feb 26 06:21:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (in_function, pop_fcall_stack, pop_fcall, push_args):
+	  New functions. These manage "frames" of awk function call arguments.
+	  The problem is that a `next' or a `nextfile' from a function
+	  leaks memory. These changes allow us to free up that memory.
+	  (interpret): for Node_K_next and Node_K_nextfile, check if in
+	  a function call and free all function call frames.

+Fri Feb 21 06:23:19 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	Misc changes from Katsuyuki Okabe <HGC02147@niftyserve.or.jp>:
+
+	* builtin.c (do_substr): Change a %d to %ld in warning message.
+	* eval.c (op_assign): Fix format string for warning about %=.
+
+Wed Feb 19 23:29:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* main.c (main): Add do_intervals to condition that causes
+	  resetup() to be called again. Makes the --re-interval option
+	  actually work. What a concept.
+
+Fri Feb 14 09:47:31 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c [#include "awk.h"]: Undef HAVE_MMAP to just use the old code.
+	  Something is causing a file descriptor leak, and this is getting to
+	  be just too much hair. I reserve the right to rip out the mmap
+	  code entirely at a future date.
+
+Tue Feb 11 06:28:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (iop_alloc): For an mmap'ed file, close the file descriptor,
+	  and then touch each page to get a private copy. Fixes nasty case
+	  of truncating our input file.
+	  (iop_close): Don't call close on mmap'ed file.
+
+Wed Feb  5 17:59:04 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (interpret): For Node_K_delete, just call do_delete; let
+	  it handle the case of `delete array'.
+	* array.c (do_delete): Changed to handle case of `delete array',
+	  and made smarter if the array is actually an uninitialized
+	  parameter.
+
+Sun Jan 26 22:58:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* getopt.h, getopt.c, getopt1.c: Replaced with new versions from
+	  GLIBC 2.
+
+Sun Jan 19 23:37:03 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (nodetype2str): Not static, for debugging.
+	  (flags2str): New function for debugging.
+	* field.c (get_field): Add new var that is like Nnull_string but
+	  does not have numeric attributes, so that new fields are strings.
+	  (set_record): Turn off PERM flag before unrefing fields and field 0.
+	* array.c (in_array): Always evaluate subscript, could have
+	  side effects.
+	* builtin.c (do_strftime): Way increase size of buffer to make sure
+	  we don't have overflow problem. Keeps Paul Eggert happy.
+	* custom.h [__amigaos__]: Define fork to vfork. From Fred Fish.
+	* dfa.c: Move include of config.h to top, for RSXNT. From Kai
+	  Uwe Rommel.
+	  (ISALPHA, etc): Change from Jacob Engelbrecht (jaen@novo.dk)
+	  to better handle non-ASCII environments.
+	* gawkmisc.c: Remove amigados case, posix should now work fine.
+	* amiga/*: Nuked per previous entry.
+	* Makefile.in: Removed all references to amiga
+	* io.c [HAVE_SYS_PARAM_H]: Add #undef RE_DUP_MAX to avoid
+	  spurious conflict with regex.h.
+	  (flush_io): Remove amiga ifdefs, not needed anymore.
+	  (spec_setup): Set getrec field for special files. Fix from
+	  Mark Gray (markgray@pdt.net).
+	* node.c (more_nodes): Fix to get the last entry in the array.
+
+Wed Jan  8 17:42:37 1997  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
+
+	* io.c (mmap_get_record): Fix return value if file ends without
+	  record separator.
+
+Fri Jan  3 19:57:16 1997  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* awk.y (get_src_buf):  Test for an empty source file by detecting
+	  an initial read of 0 bytes rather than by relying on info from
+	  stat().
+
+Wed Dec 25 11:25:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Release 3.0.2: Release tar file made.
+
+Wed Dec 25 11:17:32 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (install, uninstall): Use $(srcdir)/patchlevel.h.
+	  Thanks to Richard Levitte, LeViMS@stacken.kth.se.
+	  (install): Remove chmod command; let $(INSTALL_PROGRAM) use -m.
+
+Mon Dec 23 20:36:59 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* custom.h (#if VMS_POSIX):  Define GETPGRP_VOID.
+
+Fri Dec 20 08:59:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* getopt.c, getopt1.c: Comment out the `#if defined (_LIBC) ||
+	  !defined (__GNU_LIBRARY__)' and `#endif' to force use of this
+	  getopt, even on systems like Linux.  This will be handled
+	  better in 3.1 / glibc 2.
+
+Thu Dec 19 22:52:39 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.y (yylex): In several places, after yyerror(), add call to
+	  exit(). Otherwise, infinite messages. This should probably
+	  be handled better.
+
+Wed Dec 18 22:42:10 1996  Darrel Hankerson  <hankedr@mail.auburn.edu>
+
+	* getopt.c (_getopt_internal): If 'W' and ';', if optind == argc,
+	  return c, don't fall through.
+
+Wed Dec 18 10:09:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* configure.in [AC_PREREQ]: Update to 2.12 in order to switch to
+	  autoconf 2.12. Lots of other files will be rebuilt automatically.
+	  [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
+	* aclocal.m4 [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
+
+Tue Dec 17 22:23:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_strftime): Fix case if format string is "".
+	  Also fix it if format is not "" but result of strftime is "".
+	  See comments in code.
+
+Tue Dec 10 23:09:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Release 3.0.1: Release tar file made.
+
+Tue Dec 10 22:39:41 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

+	  does makeinfo.
+	  (install): Use $(LN) not $(LN_S) to link gawk gawk-version.
+
+Sun Dec  8 07:53:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (gawk): Took COMPFLAGS out of link line for help
+	  on VMS posix. Shouldn't (I hope) affect anything else.
+
+Thu Nov 28 11:52:24 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* configure.in (AC_PROG_INSTALL): Set INSTALL to install-sh.
+
+Tue Nov 26 22:42:00 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* PORTS: Updated list of systems.
+	* Makefile.in (install): Fix some typos and add some improvements
+	  for Ultrix.
+
+Sun Nov 24 22:16:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_printf): If no args, fatal error. Return silently
+	  if --traditional.
+
+Thu Nov  7 20:54:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (inrec): Make sure EOF hasn't already happened before
+	  trying to read; prevents accessing freed buffer. Thanks to
+	  Michal Jaegermann.
+	* Makefile.in [AWKSRC]: Add random.h.
+	* random.h: New file, redefines names of the `random' functions.
+	* random.c, builtin.c: Add include of random.h.
+
+Thu Nov  7 09:06:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.y (snode): Undo 4 Oct change, put do_split code back.
+	* field.c (do_split): Restore old code; add test for CONST, so
+	  that re_parse_field is used if third arg to split is a regexp
+	  constant.
+
+Mon Nov  4 12:57:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* main.c (main): Research -m[fr] options don't need literal '='
+	  characters. Brian's documentation was confusing.  Fixed, not
+	  that anyone actually uses these options with gawk.
+
+Sun Nov  3 11:23:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* field.c (def_parse_field): Add \n to list of acceptable white space.
+	  (posix_def_parse_field): New routine, just like def_parse_field(),
+	  but only allows space and tab as separators.
+	  (do_split, set_FS): Make appropriate choice between the two
+	  *def_parse_field() routines.

+
+Tue Oct 22 21:27:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c [GAWK_RANDOM_MAX]: Try to make definition a bit
+	  smarter; don't use RAND_MAX if it's equal to SHRT_MAX, blows
+	  things up.
+
+Tue Oct 22 08:49:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* main.c (copyleft): Update copyright date to 1996.
+	* Too many files to list: Update copyright date to 1996.
+
+Sun Oct 20 12:21:09 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.y, dfa.c, eval.c, io.c, re.c: Added various FIXME comments.
+
+Sat Oct 19 22:06:42 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (nodetype2str): Make static, add prototype.
+	* field.c (sc_parse_field): Cast array subscripts to int to
+	  shut up gcc warnings.
+	* gawkmisc.c: Add prototype for xmalloc.

+	  to shut up gcc warnings.
+	* awk.y (isassignable): Add a default to switch to quiet gcc.
+	* getopt.c (_getopt_internal): Give default value to `indfound'.
+
+Fri Oct 18 09:00:49 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* regex.h [RE_SYNTAX_AWK]: Add RE_CONTEXT_INDEP_ANCHORS.
+
+Thu Oct 17 22:32:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* aclocal.m4 [AM_SANITY_CHECK_CC]: Added.
+	* configure.in: Use it.
+
+Thu Oct 17 21:43:25 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* configure.in: Add checks for locale.h and setlocale().
+	* awk.h: Include locale.h and define out setlocale() if not available.
+	* main.c (main): Call setlocale().
+	* builtin.c (do_tolower, do_toupper): Use unsigned char pointers,
+	  to get other charsets right in different locales.
+
+Wed Oct 16 21:32:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (format_tree): Change initial buffer size to 512
+	  and use a constant. Allows large values of %f per bug report
+	  from sheyn@cs.bu.edu.
+
+Wed Oct 16 21:22:08 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in [MISC]: Removed TAGS and tags.
+	  (local-distclean): Added TAGS and tags.
+	  (maintainer-clean): Removed TAGS and tags.
+
+Wed Oct 16 12:28:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* main.c (version): Add call to copyleft(), per new standards.
+	  version.c: Fix text of version string to match new standards.
+
+Sun Oct  6 22:19:45 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* regex.c: Updated to Emacs 19.34b base.
+
+Sun Oct  6 21:57:34 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* re.c (make_regexp): Fixed to handle \8 and \9 in the middle
+	  of a regexp.
+
+Fri Oct  4 10:26:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.y (snode): Remove case for do_split; always making the
+	  third arg a Node_regex is wrong.
+	* field.c (do_split): Rationalized to distinguish `/ /' from `" "'.
+	  Generally fixed up.
+	* node.c (parse_escape): Allow single digit \x escapes.
+
+1996-10-02  Paul Eggert  <eggert@twinsun.com>
+
+	* builtin.c (format_tree): Fix bug in %d and %i format: NaNs, and
+	  values in the range LONG_MAX+1 .. ULONG_MAX, were mishandled.
+	  Don't assume that double values <= -1 are converted to unsigned
+	  long in the expected way; the C Standard doesn't guarantee this.
+
+1996-10-02  Paul Eggert  <eggert@twinsun.com>
+
+	* awk.h (INT_MAX): Remove unused symbol.
+
+Mon Sep 30 22:19:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* getopt.c (_getopt_internal): If 'W' is in the optstring followed
+	  by a ';' then search through the long opts table. This makes
+	  `-W foo=bar' same as `--foo=bar'.
+	* main.c (main): 'W' now prints an error message.
+	  (gawk_option): Deleted the routine.
+
+Sun Sep 29 23:04:54 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (sub_common): Fix several bugs with gsub when
+	  matching null strings. See test/gsubtest.awk.
+
+Fri Sep 20 17:35:54 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* alloca.c (NULL): Don't define if <config.h> has already done so.
+
+Fri Sep 20 11:54:31 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_print): Evaluate all the expressions first and
+	  then print them. Avoids surprising behavior. See test/prtoeval.awk
+	  for an example.
+
+Tue Sep 10 06:21:40 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.h [FUNC]: New flag, marks a Node_parameter_list as really
+	  being the function name; allows more checking in awk.y.
+	* awk.y (isassignable): Now takes a NODE * instead of a type, to
+	  check if a function parameter is marked FUNC, then it's the function
+	  name, which is not assignable. Fix call from snode().
+	  (function_prologue): Mark function name as FUNC.
+	  (yyerror): Don't call exit() anymore; gawk will now report
+	  all syntax errors.
+
+Sun Sep  1 19:36:30 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* field.c (rebuild_record): After building new field 0, go through
+	  all old fields, and if they used to point into the old one,
+	  have them point into the new one.  Then turn off PERM flag before
+	  unref-ing field 0.
+
+Wed Aug 28 19:13:34 1996  Arnold D. Robbins  <arnold@math.utah.edu>
+
+	* eval.c (set_IGNORECASE): Correctly parenthesize bit operations
+	  in test and fix logic for string value.
+
+Wed Aug 28 22:06:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* main.c (usage): Add email addresses for bug reporting, per
+	  change in GNU Coding Standards from RMS.
+
+Sun Aug 11 23:13:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (install): Correct use of $(INSTALL_PROGRAM).
+
+Thu Aug  8 23:29:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* parse.y (isassignable): New function, checks in type can
+	  be assigned to.
+	  (snode): Changed checking for 3rd arg of gsub to be more
+	  general, supersedes earlier change.
+
+Thu Aug  8 13:58:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* parse.y (snode): If third arg to sub or gsub is builtin
+	  function, complain, since can't substitute into result.
+	* eval.c (r_get_lhs): Diagnose Node_builtin as an error, instead
+	  of falling through into default case and using cant_happen().
+
+Thu Aug  1 07:13:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* regex.h [RE_DEBUG]: New macro.
+	  [RE_SYNTAX_GNU_AWK]: Add RE_DEBUG.
+	  [RE_SYNTAX_POSIX_AWK]: Add RE_INTERVALS.
+	* regex.c (re_set_syntax): Add #ifdef DEBUG code to turn on `debug'
+	  flag if RE_DEBUG set, and turn off debug if not set and debug
+	  was on.
+	* main.c (main): Remove `do_intervals = TRUE' from `if (do_posix)',
+	  it's now handled in the definition of RE_SYNTAX_POSIX_AWK.
+
+Mon Jul 29 17:49:07 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* io.c (O_ACCMODE): Define it if <fcntl.h> doesn't.
+
+Mon Jul 29 12:02:48 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (set_IGNORECASE): Made somewhat smarter. gawk -v IGNORECASE=0
+	  was acting the same as -v IGNORECASE=1. Thanks to Darrell Hankerson
+	  for the bug report.
+
+Fri Jul 26 12:04:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.h (format_val): Add declaration of new routine.
+	* node.c (format_val): New routine, abstracts old guts of
+	  r_forcestring; accepts format string and index as additional params.
+	  (r_force_string): Changed to call format_val.
+	* builtin.c (do_print):  Don't tree_eval the tree twice in case
+	  OFMTidx != CONVFMTidx; doing so could cause side effects
+	  (from bug report by Tobias Rettstadt, xassp@ipds.uni-kiel.de).
+	  Instead, call format_val.
+
+Mon Jul 22 21:59:15 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (iop_close): Change check for "is $0 in the input buffer"
+	  to use `< (iop->buf + iop->secsiz + iop->size)' instead of
+	  `< iop->end'. The latter is bogus if EOF has been hit on the
+	  file.  Fix from Darrel Hankerson based on bug report by
+	  Charles Howes (howes@grid.direct.ca).  See test/eofsplit.awk.
+
+Thu Jul 18 19:43:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (sub_common): Backed out change of Feb 14 in favor of:
+	  (do_gensub): Changed to use make_string and then to |= TEMP
+	  flag, based on bug report and patch from Katsuyuki Okabe,
+	  hgc02147@niftyserve.or.jp.
+
+Thu Jul 18 19:23:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* custom.h: Added ifdef for QNX, based on bug report from
+	  Michael Hunter, mphunter@qnx.com.
+
+Mon Jul 15 09:31:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (redirect): When finding the rp pointer, if it's not
+	  NULL, set str = rp->value. This gets the '\0' terminated
+	  version. Motivated by bug report from John Hawkinson
+	  (jhawk@bbnplanet.com).
+
+Sun Jul 14 18:40:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* configure.in: Added call to AC_CHECK_LIB(m, fmod), since
+	  apparently some systems have fmod in the math library.
+	  Portability: The Holy Grail.  Sigh.
+
+Sun Jul 14 18:08:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.h: Add Jim Meyerings ISASCII etc hacks for ctype macros.
+	* builtin.c (do_toupper, do_tolower, sub_common): Changed to use
+	  upper-case versions of ctype macros.
+	* main.c (main): Ditto.
+	* node.c (r_force_number, parse_escape): Ditto.
+
+Sun Jul 14 06:34:18 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* field.c (set_record): Made it always do the PERM flag.
+	  Fixes cases where $0 is assigned to, e.g. by gsub, keeps
+	  the fields valid.
+	  (get_field): Removed the call to reset_record in
+	  case where ! field0_valid. We want to leave the fields alone
+	  if they've been changed.
+
+Thu Jul 11 23:04:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (devopen): Change tests of (flag & O_fooONLY) to
+	  (flag & O_ACCMODE) == O_fooONLY. Per (long standing) bug
+	  report from Chapman Flack.
+	  (close_redir): Change final conditional to just (status != 0)
+	  so that ERRNO always set; the warning had its own `if (do_lint)'
+	  anyway.
+	* eval.c (do_split): Force type of array to be Node_var_array
+	  instead of Node_var.  Per (long standing) bug report from
+	  Chapman Flack.
+
+Thu Jul 11 22:17:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (install): Added symlink of gawk to awk if
+	  no awk in $(bindir).
+	  (LN_S): New variable for symlinking.
+	  (uninstall): Remove awk if it's the same gawk.
+	* Configure.in: Added call to AC_PROG_LN_S for Makefile.in.
+
+Sun Jul  7 15:47:13 1996  Arnold D. Robbins  <arnold@infographix.com>
+
+	* main.c (main): Made `--posix' turn on interval expressions.
+	  Gawk now matches its documentation. (What a concept!)
+
+Wed Jul  3 15:02:48 1996  Arnold D. Robbins  <arnold@infographix.com>
+
+	* regex.h, regex.c: Upgraded to changes from Emacs 19.31.
+
+Fri May 17 08:46:07 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (get_a_record): Added `continued' flag. Fix from
+	  Darrell Hankerson for when RS = "\n|something".
+
+Wed May 15 02:34:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (awklib/all): Now depends on gawk, fixes problem
+	  with parallel make.
+
+Tue May 14 15:02:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (format_tree): Fix handling of '*' to deal with
+	  negative value for fieldwidth -- make positive and turn on
+	  left justify. Per bug report from Michael Brennan.
+
+Sun May 12 20:42:06 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* eval.c (r_get_lhs): case Node_subscript. Check if array name
+	  is actually a function, fatal error if so.
+
+Sun May  5 10:11:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (redirect): Call flush_io() before creating a new output pipe,
+	  per bug report from Brian Kernighan (bwk@research.bell-labs.com).
+
+Fri Mar 15 06:38:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (install): Use $(INSTALL_PROGRAM), not $(INSTALL).
+	  (local-distclean): Add `*~' to list of files to be removed.
+	  (CFLAGS): Now contains just @CFLAGS@.
+	  (COMPFLAGS): Replaces use of CFLAGS, has CFLAGS plus all the
+	  other stuff.
+
+Wed Mar 13 14:19:38 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (mmap_get_record): Fixed to not place sentinel at end
+	  of mmap'ed object. Won't work if file is exact multiple of
+	  disk block size. See comments in code for more info.
+	  Thanks to Rick Adams (rick@uunet.uu.net) for help in testing.
+
+Sun Mar 10 22:50:23 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* io.c (do_close): Notice if we were called as `close(FILENAME)'
+	  and arrange to close the current input file. This turns out
+	  to be easy to do, just call `nextfile(TRUE)'. Based on bug report
+	  from Pascal A. Dupuis, <dupuis@lei.ucl.ac.be>.
+
+Thu Mar  7 08:08:51 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* field.c (init_fields, grow_fields, set_field, rebuild_record):
+	  Nuke the `nodes' array everywhere.  Anytime a field is unref'ed,
+	  allocate a new node that is a copy of Nnull_string. This avoids
+	  subtle memory management problems when doing a lot of assignment
+	  to fields, and tweaking of NF. Make sure that fields_arr[0] always
+	  has a type of Node_val!
+	* field.c (set_NF): If NF is decremented, clear fields between
+	  NF and parse_high_water, otherwise if NF incremented, clear
+	  fields between parse_high_water and NF.
+	* eval.c (nodetype2str): New function, used for diagnostics.
+	  (interpret): Use nodetype2str when finding invalid node.
+
+Mon Mar  4 09:02:28 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_toupper, do_tolower): Use isascii along with
+	  isupper/islower before changing case, in case characters have
+	  the high bit set. This is a hack.
+
+Mon Feb 26 22:24:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (sub_common): If no match, and called from gensub,
+	  don't free the temporary string, since the tmp_number then
+	  writes over it.
+
+Sun Feb 25 23:13:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (format_tree): Fixed %c to treat user input as
+	  numeric also by adding test for MAYBE_NUM.
+
+Tue Feb 20 12:25:50 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* configure.in: Added AC_FUNC_MMAP call and add madvise to
+	  list of functions to look for.
+	* awk.h [IOP_ISMAPPED]: New flag value for mmap support and new
+	  `getrec' structure member in struct iobuf.
+	* io.c (iop_alloc, iop_close): Changed to map/unmap input file
+	  into memory if possible.
+	  (mmap_get_record): New function to actually retrieve the
+	  record from mmaped file.
+
+Thu Feb  1 08:56:46 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_substr): Fixed lint message to use indx+1 when
+	  start position is past end of string.
+
+Sun Jan 28 07:00:56 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_substr): Rationalized handling of missing length
+	  argument, as well as various accompanying lint warnings. Previous
+	  code was slightly bogus. Talk about your Day 1 bugs.
+
+Thu Jan 25 14:09:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* builtin.c (do_substr): If length exceeds length of actual
+	  string, do computation of needed substring length *after*
+	  the lint warning.
+
+Wed Jan 24 10:06:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Makefile.in (gawk): Add $(CFLAGS) to link line.
+	  (Makefile): Target depends on the Makefile.in files.
+	  (OTHERS): Added TAGS and tags to the distribution.
+	  (local-distclean): New rule.
+	  (distclean): Use it.
+	  (maintainer-clean): Don't `make distclean' before running submakes,
+	  since that removes makefiles needed for the submakes.
+	* builtin.c (do_strftime): Remove hard coded limit on length of result.
+	  Based on code from Paul Eggert (eggert@twinsun.com).
+
+Mon Jan 22 13:16:37 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* main.c (usage): Takes new fp parameter which is either
+	  stdout for `--help' (per the GNU Coding Standards) or stderr
+	  if an error occurs. Fix all calls.
+	  (version): Prints to stdout per the coding stds.
+	  (copyleft): Prints to stdout now, not stderr, and exits.
+
+Fri Jan 19 08:10:29 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* regex.h [RE_GNU_AWK]: Added RE_CONTEXT_INDEP_OPS to set of
+	  bits we turn off for regular operation. Breaks things like
+	  /^+[0-9]+/ to match a literal `+' at the beginning of, say,
+	  a phone number.
+
+Wed Jan 10 23:19:36 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* 3.0.0 polished up and release tar file made.
+
+Wed Dec 27 11:46:16 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* 2.94.0 released to porting group (no, I haven't been good
+	  about this file; I'll do better once 3.0 is released).
+
+Mon Aug 28 23:04:30 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* awk.h updated for NeXT - bracket TRUE/FALSE
+	* io.c (get_a_record): Removed shadowing of 'start' in
+	* Makefile.in and doc/Makefile.in: Fixed to use gawk.1 and gawk.texi,
+	  instead of gawk.1.in and gawk.texi.in.
+
+Mon Aug 25 11:04:30 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* 2.90.0 released to porting group.
+
+Fri Aug 18 12:43:31 1995  Arnold D. Robbins  <arnold@puny.ssc.com>

+Thu Nov 12 21:01:24 1998  Darrel Hankerson   <hankedr@mail.auburn.edu>
+
+	* mingw32 target added with corresponding minor changes to getid.c,
+	  io.c, and config.h.
+	
+	* vcWin32 needed popen defines in config.h which were inadvertently
+	  omitted from 3.0.3.
+
+	* README.pc updated to clarify the procedure for building
+	  non-LFN versions on LFN systems, and to note that Windows32 gawk
+	  may require Windows32 utilities.
+
+	* emxbnd target modified to accomodate older versions of emx.
+
+Thu Nov 08 09:11:44 1998  Scott Deifik       <scottd@amgen.com>
+
+	* pc/Makefile: Stack reduced again for 16bit MSC versions.
+	  
+	* pc/Makefile.tst: Updated to keep in sync with new
+	  test/Makefile.in.  In addition, made to work in Windows 9x
+	  with non-LFN tools.
+
+Thu May 15 12:49:08 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* Release 3.0.3: Release tar file made.
+
+Tue May 13 20:06:09 1997  Darrel Hankerson  <hankedr@mail.auburn.edu>
+
+	* vcWin32 target added.  Some new tests for WIN32 in gawkmisc.c
+	  io.c, and regex.c.  Makefile changes for nmake, which can't 
+	  expand $($x).
+
+	* config.h updated for BITOPS and NONDECDATA (also in Makefile).
+
+Fri Apr 18 07:55:47 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>
+
+	* BETA Release 3.0.34: Release tar file made.
+
+Fri Jan 17 19:20:45 1997  Darrel Hankerson  <hankedr@mail.auburn.edu>
+
+	* Makefile: add KUR's emxnt target for emx+RSXNT.  Create awk.exe
+	  "link" to gawk.exe for djgpp target.  (Suggested by Eli Zaretskii.
+	  Should be done as part of a smarter install, since awk.exe only
+	  works with djgpp gawk.exe.)  Separate djgpp-v1 into djgppv1 
+	  target.  Install awk.exe if present.
+
+	* install.awk: install awk.exe if present (only for djgpp)
+
+	* config.h: additional include for emx+RSXNT.

-	carriage-return-carraige-control record attribute along with
-	stmlf foramt.  gawk failed on an internal redirection attempt

-	file existed with conflicting attributes and the program was
-	built using DECC$SHR run-time library rather than VAXCRTL.
-
-	* vmstest.com: Add over 70 new tests.  Overhaul how lists of
-	tests are specified and executed.  Make many similar tests run
-	with shared commands instead of maintaining separate code for
-	each one.  Put output for 'test' into "_'test'.tmp" instead of
-	"tmp." so that it's easier to investigate if/when multiple test
-	failures occur in the same run.

-	(HAVE_ATEXIT): Define.
-
-Tue Jan 27 21:49:53 2009  Arnold D. Robbins  <arnold@skeeve.com>
-
-	Per Pat Rankin based on changes to awk.h and change in main code
-	to use EXIT_SUCCESS / EXIT_FAILURE from Toni Schilling
-	<Schilling@equicon.de>.
-
-	* redirect.h (exit): Remove definition.

+
+Fri Apr 29 18:10:49 2011  Pat Rankin  <rankin@pactechdata.com>
+
+	* gawkmisc.vms (os_isatty): New routine.

+
+	* vms_gawk.c, gawk.cld: Add support for new command qualifiers:

+	/usage, /version, /copyright    try harder to make awk program and
+	data file be optional since these just give messages and then quit.
+	(vms_usage): Substitute "GAWK", "DGAWK", or "PGAWK" as appropriate
+	for command name when issuing the VMS-specific usage message.
+	* vms.h (CLI$_NEGATED): Define macro (from <cilmsgdef.h>).

+
+Tue Jan 18 17:51:07 2011  Pat Rankin  <rankin@pactechdata.com>
+
+	* vms_args.c (vms_arg_fixup): If AWK_LIBRARY lacks a value, define
+	it as "SYS$LIBRARY:" so that the default value of AWKPATH ends
+	with a valid directory.  Needed so that gawk -f no-such-file
+	will report "file not found" or "no such file or directory"
+	instead of "file specification syntax error".
+
+	* vms-conf.h: Sync with configh.in; define HAVE_STRCOLL as 1.

+	(PACKAGE_URL): add #undef as placeholder.
+
+Wed Jan  6 19:05:05 2010  Pat Rankin  <rankin@pactechdata.com>
+
+	* vms_fwrite.c (tty_fwrite): Check which_gawk, and stick to
+	ordinary fwrite() when it's exe_debugging because dgawk uses
+	other stdio calls besides fwrite for terminal output, and that
+	wouldn't interleave sanely with tty_fwrite()'s terminal output.
+
+Wed Jan  6 19:05:05 2010  Pat Rankin  <rankin@pactechdata.com>
+
+	* awk.h (exe_mode): Define new enum: exe_gawking for regular gawk,
+	exe_debugging for dgawk, and exe_profiling for pgawk.
+	(which_gawk): Declare new variable.
+	* eval.c (which_gawk): Define it.
+

+
+	* vms_misc.c (vms_open): Explicitly specify "rat=cr" to force
+	carriage-return-carraige-control record attribute along with
+	stmlf foramt.  gawk failed on an internal redirection attempt
+	(``print anything > file'') if an earlier version of the output
+	file existed with conflicting attributes and the program was
+	built using DECC$SHR run-time library rather than VAXCRTL.
+
+	* vmstest.com: Add over 70 new tests.  Overhaul how lists of
+	tests are specified and executed.  Make many similar tests run
+	with shared commands instead of maintaining separate code for
+	each one.  Put output for 'test' into "_'test'.tmp" instead of
+	"tmp." so that it's easier to investigate if/when multiple test
+	failures occur in the same run.
+	(vms_io2): New test to check the ``print anything > file'' fix.

+
+Tue Jan 27 21:49:53 2009  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Per Pat Rankin based on changes to awk.h and change in main code

+
+	* redirect.h (exit): Remove definition.

+
+Sun Apr 29 18:09:17 2007        Pat Rankin      <rankin@pactechdata.com>
+
+	* redirect.h: declare snprintf() if CRTL_VER_V732 is defined;
+	redefining __CRTL_VER in config.h causes <stdio.h> to suppress it.
+
+	* vmstest.com (fnarray): exit code has changed to 2.
+	(pid): target values now passed by command line rather than file.
+
+Fri Apr 20 16:48:30 2007        Pat Rankin      <rankin@pactechdata.com>
+
+	* vms-conf.h: #define HAVE_SNPRINTF for V7.3-2 and later CRTL.
+	* redirect.h: #define snprintf to gawk_snprintf if we're using
+	  missing_d/snprintf.c; avoids diagnostic about its declaration.
+
+Thu Apr 12 18:59:33 2007        Pat Rankin      <rankin@pactechdata.com>
+
+	* vms-conf.h: Leave HAVE_MKSTEMP undefined; we want tmpfile().
+
+Thu Mar 29 19:30:20 2007        Pat Rankin      <rankin@pactechdata.com>
+
+	* vms-conf.h: reconcile with configh.in.
+
+	* descrip.mms: compile floatcomp.c; add pgawk target and build
+	pgawk.exe for `make all'.
+	* vmsbuild.com: compile floatcomp.c; always build pgawk.exe in
+	addition to gawk.exe.
+
+Wed Jul 27 21:31:14 2005        Pat Rankin      <rankin@pactechdata.com>
+
+	* vmstest.com: Format test group feedback differently (append "...")
+	  to distinguish it from individual test feedback.
+	(manyfiles): Determine the number of files to use dynamically
+	  instead of using hardcoded 300 in case user's open file quota
+	  is generous enough to support more than that.

+	  VAXCRTL doesn't cause testing to terminate.
+	(vms_io1): Invoke with normal Unix-style command line syntax.

+
+	* vms_args.c (vms_arg_fixup): for the 2>&1 case, don't set the

+	  empty file being created.

+	  inherit its record format from any earlier version of that file.

+

+	  rely on <stat.h> to do so.  There are too many DEC C version
+	  variants to handle otherwise.
+
+	From Martin Zinser <zinser@axp602.gsi.de>:
+
+	* descrip.mms (gawk.dvi):  update to build in [.doc] directory
+	  using texindex.c retained from an earlier gawk 2.x distribution.

+
+Thu Dec 19 17:49:31 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* redirect.h (strcasecmp, strncasecmp, tzset, tzname,

+	  declarations (which might have trailing elipsis).
+	* vms_misc.c (tzset, tzname, daylight, timezone, altzone):

+
+Fri Dec  6 20:55:57 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* redirect.h, vms-conf.h:  Refine Sep 20th change:  include
+	  <stdlib.h> and <string.h> in redirect.h rather than vms-conf.h
+	  so that it occurs for VMS POSIX as well as for normal VMS.
+
+Wed Nov 20 15:47:02 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* descrip.mms (LIBOBJS): Rename from GNUOBJS; add random.obj.

+	  (random.obj, builtin.obj): Depend upon random.h.
+	* vmsbuild.com: compile random.c, link random.obj.
+
+	* vmstest.com (childin): Split message about expected failure
+	  in order to avoid consecutive tick marks in the quoted string.
+
+Wed Nov 13 15:32:58 1996  Pat Rankin  <rankin@eql.caltech.edu>
+
+	* vmstest.com: New file to execute test suite.

+
+	Revise makefiles so that no editing should be needed.
+
+	* descrip.mms: Use DEC C as the default compiler, since

+	* vms_*.c: Use them.

+	just declare them.

+
+	* vms-conf.h: directly include <stdlib.h> and <string.h>.

+	(_DECC_V4SOURCE, __SOCKET_TYPEDEFS):  Define these to avoid
+	duplicate u_long and u_short typedefs.
