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
