    Rename GNOME_COMPILE_WARNINGS to just COMPILE_WARNINGS.
    
    Poaching someone else's macro name is a really dumb idea, because aclocal
    looks in our macros directory only if it can't find the macro in the system
    directories. Our config code doesn't work with Gnome's macro, it exports
    WARN_CFLAGS rather than modifying CFLAGS directly the way ours does.
