AVS 3.0 : ACM and mingw

[d'Oursse]

Hello,

We are working on the audio part for avisynth 3.0, and we want to compile it with mingw.

For the audio part, on windows, we use ACM. But mingw has some lacks with handling ACM, and more precisely, the ACM streams.

We want to use the following functions:
acmStreamOpen
acmStreamClose
acmStreamSuggest
acmStreamPrepare
acmStreamConvert
acmStreamUnprepare

(in addition to some defines and structs)

so, does someone know something about ACM streams on mingw ?

any hint is welcome :)
