395b07d1df 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>.

4cf61aba29 Fix grammar to eliminate support for unary minus expressions -- they
weren't supported, they aren't standard, and they caused expr to dump
core.

55c497bf15 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.
