I proposed two patches but there is a question that maybe Andy could
answer : what is the purpose of fgOSExit ? It comes to me because
this function, is called only once in FlightGear while exit is called
at many locations. fgOSExit is just calling exit for the glut version
and SDL_Quit() + exit in the sdl version.
What about calling SDL_Quit in a function installed by 'atexit', remove
fgOSExit and only rely on exit in all the program ?
