I'm not seeing it, on whatever random version of RH we had on a machine
here, and haven't seen it on the Debian 2.2 on one of my home machines.

I'd say the problem has nothing to do with NEED_GETOPT_H being defined;
it has to do with gtk/main.c and gtk2/main.c not including <unistd.h>,
as the Single UNIX Specification says you should include <unistd.h> if
you're using "getopt()".  I've checked in a change to make them both do
so.
