Which is probably a bug in itself - I end up removing @symbol_visibility@
from xorg-server.pc.in when building our packages, since we support both
gcc & Sun Studio, and they take different flags for that option.

I tend to agree, providing compiler flags such as this one is pushing the "convenience" envelop. This flag should be specified in the driver module, but it is significant work. There is no facility to specify a portable compiler flag. In this particular case, it could be supplied through a server macro and included in each driver makefile. <BR>

If we are willing to make the assumption that no other modules will pass a compiler flag in pkgconfig, then we can have pre-processor/compiler flags separation in apps and libs. <BR>

As a side note, it looks like the server config handles the SUN compilers.<BR>
