GLXPbufferSGIX and GLXPbuffer are not defined anywhere in my nVidia GL headers although they are used throughout the GL headers!
I've checked Mesa - same thing.

The following lines in extensions.hxx cause a problem because GLXPbufferSGIX is not defined.

#ifndef GLXPbuffer
#define GLXPbuffer GLXPbufferSGIX
#endif

Ok, this is be fixed in CVS now.

This is confusing.
Are GLXPbuffer and GLXPbufferSGIX both supposed to be programmer defined?

PBuffers once was *the*way to get accelerated support for texture rendering. It has been superseded by a number of other extensions of which the official RenderTexture extension is the preferred way now. Unfortunately our implementation doesn't have support for that one (yet).
