--- Comment #3 from Marcus Meissner  ---
yes, the calling convention is mismatched.

we forward to the Linux opengl, which does a UNIX cdecl callback instead of a
Win32/Win64 WINAPI callback.

It needs to be moved out of the auto-generated functions into wgl.c and
implemented seperately. (a bit tricky due to the autogeneration of the code)
