[Mesa3d-dev] Windows and 3.3 question

[<me...@bi...>]

I got mesa 3.3 working on Windows (built and linked to opengl32.dll).
One more bit of difficulty I ran into was with header inclusion order.

- glapi.c needs a bunch of prototypes for extenstions to compile
  correctly. 
- glext.h has them, but they only get compiled in if
  GL_GLEXT_PROTOTYPES is defined.

The chain of inclusion with glapi under Windows/MSVC goes like this:

 glapi.c includes glheader.h,
   which includes mesa_wgl.h,
   which includes gl/gl.h,
   which includes gl/glext.h (since GL_GLEXT_LEGACY is not defined).

But nowhere in there does GL_GLEXT_PROTOTYPES get defined. It currently
gets defined in glheader.h just AFTER the inclusion of mesa_wgl.h
after which glheader includes gl.h and glext.h directly.  So I fixed
by defining GL_GLEXT_PROTOTYPES it just before #including mesa_wgl.h in
glheader.h.  Sound ok?
