+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.
