-; 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.
