Now I have osmesa+llvmpipe with mangling enabled on both Linux and Mac. Is
there any way to have it on Windows? With cross compiling, I can have a
multi-threaded gdi driver. But not osmesa.

Ahh. You are righ. That fixes it.

Looks like your code is not finding any mgl*() prototypes. What
#includes do you have? I think you need to #include "GL/gl_mangle.h"
and then "GL/gl.h", IIRC.
