It went fine to make the Mesa libraries.

Is there a way to switch off certain parts of the X server, i.e. support for those graphics cards that never 
will be found in my Apple PowerBook?

Mac OS X 10.4.7, GCC 4.0.1

As this states quite clearly, this is a bug in the compiler, not our code.

You should be able to avoid this with configure --disable-glx.
