Changes:
- eliminate some fixed limits on buffer sizes (prompted by FreeBSD port).
- eliminate fixed limit on include nesting.
- use configure check for mkstemp(), use that function in preference to
mktemp() if a working version is found.
- move strstr.c into strkey.c to avoid zero-length object
- improve configure check for gcc version, from ncurses.
- update config.guess, config.sub
