I guess your using the wrong 'calling convetion'. You should change the
setting  to 'stdcall' in the 'Project settings-> C/C++ -> Code
generation -> Calling convetion'. This should fix your problem.

It is a "bug" in the gl.h (the function prototypes are wrong) included
in the Mesa. The latest sources available at Mesa CVS should not include
this bug.

BTW, the easiest way to use Mesa under Win is to link with the standard
Microsoft Opengl32.lib and to copy the Mesa DLLs in the directory where
you run your application (so it is also very easy to switch between Mesa
and system OpenGL, you have only to delete or copy the Mesa DLLs).
