fcntl.h has been in bsd since 4.2, in AT&T since system III, in SunOS since
it was called Sun UNIX, and in linux since presumably its start. Since it's
clearly in windows a well, it should be safe to include it everywhere needed
with no configure test or #ifdef logic.
string.h has been in bsd since 4.4bsd, and in AT&T since system 5. It
wasn't in 4.2bsd, sunos, etc, but as people have pointed out
this probably doesn't matter. I doubt there are any supported platforms
for AFS where there needs to configured ifdef logic when including it.
