Brian, this may solve the problem for the current subset of
extensions, but is merely a hack. Silently including glext.h from gl.h
changes established semantics for including gl.h. It should be up to
the application at compile-time to decided whether it wants those
changed semantics or not. Let's not minimize the problems, but instead
address the real issue.
