GTK and GLIB are perfectly portable, but the IRIX MipsPRO C compiler is
not completely compatible with gcc. /usr/local/include/glib.h includes
/usr/local/lib/glib/include/glibconfig.h which contains all sorts of
*compile time* dependencies.

If you compiled GLIB with gcc and try to compile another C program with
IRIX cc, things may break. The other way around might work (compile GLIB
with IRIX cc, compile other programs with gcc) because gcc has a superset
of IRIX cc's features.

Anyway: unless you really need MipsPRO's nifty automatic parallelisation
features (-mp -pca), you could just stay with gcc. The latest gcc-2.95.2
generates code which is as fast as MipsPRO C, so performance loss is no
longer an issue. Gcc has much more warnings, and the warning (and error)
messages are much clearer.
