expr(1) didn't comply to Posix.2 and its own man page: any
...
comparisions have been made as string comparisions, even in cases
where both operands clearly qualified as integers.
The fix is to make the parser properly analyzing whether an operand is
a valid integer or not.

You will find enclosed some changes to make gcc -Wall more happy in
...
/usr/src/bin. Note that some patches are still needed in that directory.
I (Joerg) finished most of Philippe's cleanup. /bin/sh will still
need *allot* of work, however.

Explicitly include <sys/types.h> before including <regex.h>. This is
...
apparently required by POSIX. It will be required in practice when
the bogus inclusion of <sys/types.h> is removed from <stdio.h>.

weren't supported, they aren't standard, and they caused expr to dump

1003.2 requires that lexical comparisons be done in locale specific manner,
...
so we have to use strcoll() instead of strcmp().
1003.2 requires that a null string be returned if a string does not match
a \( \) subexpression.
Replaced fprintf/exit with calls to err and errx as appropriate.
