----------------
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.
