[Mesa3d-dev] Re: SET_IMMEDIATE macro in tnl/t_context.h

[Li M. <mi...@mp...>]

This problem happens when I use
make -f Makefile.X11 irix6-n32-dso (gcc is the compiler)

It will disappear when using
make -f Makefile.X11 irix6-gcc-n32-sl (gcc is the compiler)

The problem "_P in types.h", which I reported shortly before,
will also go away if using gcc.
