Useless SDL_mixer functions?

Mix_SetSynchroValue and Mix_GetSynchroValue seem completely useless…

does anyone use these functions? all they seem to do is set/get an int in the mikmod stuff.
the same int is not used elsewhere in the mikmod stuff as far as I can see…

I’m thinking this is pretty dead code!
can anyone say otherwise?
is this just for backwards compatibility, or some newer version of libmikmod that SDL_mixer doesn’t use?–
