SDL_mixer reads loop information from WAV files if you use the Mix_Music interface, but NOT the Mix_Chunk interface. So bgm now uses the Mix_Music interface to get proper looping. There's also some code here for reading bgi files (taken from xsystem35) but it's not actually used. There doesn't seem to be a simple way to set up custom loops with SDL_mixer.
