	It looks like something prior to inclusion of
/usr/include/pthread.h is confusing the GCC preprocessor.  My guess is
that glib-1.2.3 does something special in its header files when __GNUC__
or some such GCC macro is defined.  The additional stuff is not seen by
AIX cc when it compiles the file.  Maybe glib is assuming something about
SVR4 or Linux, but something is wrong with its files in the presence of
GCC.
