Then you should not be observing this problem. (And in fact, I'd expect
the patch applied for Fink to cause things to break when built against
that header.) The problem is with glu.h where the declaration of
gluTessCallback looks like this:

        void gluTessCallback(GLUtesselator* tess, GLenum which,
                             GLvoid (*CallBackFunc)(...));
