SiliconExarch 4f0c54f63f Fix compatibility with Mac OSX 10.4 and 10.5
- Fix build with SDL <=2.0.3
  SDL_GetGlobalMouseState was introduced in 2.0.4
  (which doesn't support OSX 10.5 or older)
- Don't include execinfo.h on Mac OS X 10.4
  This file isn't included in the 10.4 SDK
- Use custom typedef for PFNGLSTENCILOPSEPARATEPROC on OSX 10.4/10.5
  because the system OpenGL headers for those versions don't have it
