Fix for bug reported by Michael Benfield on the SDL mailing list: "I'm on Mac OS 10.3.9 with a CVS SDL 1.2.9. My understanding is that SDL_CDResume is supposed to resume play after calling SDL_CDPlay. It doesn't on my system. It returns 0 but nothing happens. Any ideas? Thanks. Mike Benfield" --ryan.
