I forgot, if you're compiling for x86 or x86-64, we use assembly 
language dispatch functions.  They're in src/mesa/x86/glapi_x86.S and 
src/mesa/x86-64.S.  It looks like the later wasn't written with the 
USE_MGL_NAMESPACE option in mind.  Feel like taking a crack at fixing 
that?

Hmmm, you might begin investigating with 'nm mesa/src/drivers/x11/*.o 
| grep SwapBuffers'
