This is actually not an issue of conformance. Mesa supports all of the core OpenGL functionality, but not all of the defined extensions. That's probably what they meant, and they are correct. But some applications want to be able to use an extension if it is available, yet fall back to a standard implementation if it is not. For these applications, the extension definitions (GL_xxx definitions, etc...) must be available at compile time, even if the implementation on the current system does not support them. In this case, XiG has a missing #define in their header, presumably for a feature which they don't support. This is wrong -- they need to include the symbol definitions, and allow applications to fail over at runtime via glXQueryExtension/glXGetProcAddress. All that being said, I'd be curious as you how your experience is with the XiG drivers. These provide the only useful Radeon support for Linux, right now, and are rather reasonably priced.
