Fixed a few issues compiling with Mac OS X 10.6 Unfortunately the audio and cdrom systems do not build at all, and if you disable those, SDL still fails to link with these errors: Undefined symbols: "_OBJC_IVAR_$_NSScreen._frame", referenced from: -[NSScreen(NSScreenAccess) setFrame:] in SDL_cocoamodes.o "_KLGetKeyboardLayoutProperty", referenced from: _UpdateKeymap in SDL_cocoakeyboard.o _UpdateKeymap in SDL_cocoakeyboard.o "_KLGetCurrentKeyboardLayout", referenced from: _UpdateKeymap in SDL_cocoakeyboard.o ld: symbol(s) not found
