-;DESCRIPTION 'Mesa (OpenGL work-alike) for Win32'

-VERSION 6.5

-;

-; Module definition file for Mesa (OPENGL32.DLL)

-;

-; Note: The OpenGL functions use the STDCALL

-; function calling convention.  Microsoft's

-; OPENGL32 uses this convention and so must the

-; Mesa OPENGL32 so that the Mesa DLL can be used

-; as a drop-in replacement.

-;

-; The linker exports STDCALL entry points with

-; 'decorated' names; e.g., _glBegin@0, where the

-; trailing number is the number of bytes of 

-; parameter data pushed onto the stack.  The

-; callee is responsible for popping this data

-; off the stack, usually via a RETF n instruction.

-;

-; However, the Microsoft OPENGL32.DLL does not export

-; the decorated names, even though the calling convention

-; is STDCALL.  So, this module definition file is

-; needed to force the Mesa OPENGL32.DLL to export the

-; symbols in the same manner as the Microsoft DLL.

-; Were it not for this problem, this file would not

-; be needed (for the gl* functions) since the entry

-; points are compiled with dllexport declspec.
