This patch fixes a compile error in the OpenGL backend. Apparently no-one has tried compiling it in more than 2 years... ;)
The was only needed for mac before SDL2 support. With SDL2 it has not been used, I think.
Maybe simsys_opengl.cc should just be deleted. It is silly, and apparently useless.

I agree. I attached a patch that removes the OpenGL backend.
