Camilla Löwy 78ad4e8f36 Fix desktop GL header not always being suppressed ... If an OpenGL ES header or the glcorearb header is included before the GLFW header (with no options defined), the legacy OpenGL header will be implicitly included and the compilation will fail. This disables the default behavior if we detect any known OpenGL, OpenGL ES or extension loader inclusion guard macro.
