annotate src/audio/disk/SDL_diskaudio.h @ 1627:aee7ea396f59

Fixed bug #179 SDL_SemValue() always returns 0. That's because the underlying POSIX sem_getvalue() is implemented as a noop in Mac OS X. Apart from that, semaphores do work properly (at least according to test/testsem), so I'm not sure if this is worth fixing at all.
