(and a bunch more).

It took me a while to figure this one out. There are conflicting “GL/internal/dri_interface.h” files – one comes from Mesa and the other one from the glproto package (version 1.4.9) which is part of the Xorg distribution. Deleting the latter (at /usr/X11R7/include/GL/internal/dri_interface.h) made the problem go away.

It is a bit strange, though; why does glproto include that header file if it’s not needed – if it is, in fact, problematic?
