I've shipped games where I built SDL_sound with gcc3.3 on PPC and gcc4.0 
on Intel, glued the two together with lipo, and was done with it.

It's not elegant, but it was the easiest solution.

Sam updated SMPEG to be Universal with the fatbuild script. We should 
probably do something similar for SDL_sound.
