Yes, the visibility cflags should probably have been added to xorg-macros
(since it's useful for libraries as well as driver modules) and the macro
added to the drivers.

Yes, so if I build the X server with Sun compilers and don't patch out that
section, no one can build drivers with gcc (including me, which is why I found
this, since some of the drivers I build cannot be built with Sun compilers and
must use gcc).
