----------------

1. POSIX leaves undefined what happens for something like

	awk '{ print ; exit }' if=42 /etc/passwd

   Mawk diagnoses this.  Gawk and BWK awk do not.

2. String comparison with <, <= etc is supposed to take the local collating
   sequence into account.  Gawk currently doesn't.  This is exacerbated
   by the fact that the standard routines all want zero-terminated
   strings to work on.

3. For printf %c, when passing a numeric value, it is converted to
   a character and printed.  I suspect that it should be converted
   to a wide-character and then that wide character's multibyte
   encoding should be printed.

   Similarly, when given a string, only the first character of the
   string should be printed. Right now it only prints the first byte.

4. Plain `length' is no longer marked obsolescent; the doc needs updating.

5. The POSIX.STD file needs updating.
