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. +; +; However, this file is still needed to export "internal" +; Mesa symbols for the benefit of the
