-/*
- * strftime.c
- *
- * Public-domain implementation of ISO C library routine.
- *
- * If you can't do prototypes, get GCC.
- *
- * The C99 standard now specifies just about all of the formats
- * that were additional in the earlier versions of this file.
- *
- * For extensions from SunOS, add SUNOS_EXT.
- * For extensions from HP/UX, add HPUX_EXT.
- * For VMS dates, add VMS_EXT.
- * For complete POSIX semantics, add POSIX_SEMANTICS.
- *
- * The code for %c, %x, and %X follows the C99 specification for
- * the "C" locale.
- *
- * This version ignores LOCALE information.
- * It also doesn't worry about multi-byte characters.
- * So there.
- *
- * This file is also shipped with GAWK (GNU Awk), gawk specific bits of
- * code are included if GAWK is defined.
- *

-Hi Arnold,
-in a process of fixing of strftime() in libraries on Atari ST I grabbed
-some pieces of code from your own strftime.  When doing that it came
-to mind that your weeknumber() function compiles a little bit nicer
-in the following form:
-/*
- * firstweekday is 0 if starting in Sunday, non-zero if in Monday
- */
-{
-    return (timeptr->tm_yday - timeptr->tm_wday +
-	    (firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7;
-}
-How nicer it depends on a compiler, of course, but always a tiny bit.
-
-   Cheers,
-   Michal
