Fixed bug 4797 - SDL fails to compile with Mesa Master (thanks Michael Olbrich!) fix building with Mesa 19.2 With Mesa 19.2 building fails with: /include/GLES/gl.h:63:25: error: conflicting types for 'GLsizeiptr' The same type is defined in include/SDL_opengl.h for OpenGL and the two headers should not be included at the same time. This was just never noticed because the same header guard '__gl_h_' was used. This was changed in Mesa. The result is this error. Fix this the same way GLES2 already handles this: Don't include the GLES header when the OpenGL header was already included. (https://hg.libsdl.org/SDL/rev/6a3670d6108d)
