okay I retract my complain about qsort vs quick_sort:
by checking the call listings, I can see that qsort is only used by FMOD functions.
So this isn't THEIR fault, this is them writing their own quicksort implementation and not using the one that comes with one of the libraries they included
hey look they've got bsearch vs mbinary_search!
And this time, it's NOT the fault of FMOD.
it's the fault of the Fonix Voicesync middleware.
