winemp3.acm: Fixes the Mac-specific code (try 2)

[Aric Stewart]

Hi,

  I was excited to try out this patch but now it is giving me a crash. 
(OS/X 10.5.8)

Here is the mpeg log snipit from just before the crash:

I am also getting quite a number of build warning that i dont know if 
should be concerning.

Anything more I can do to test for you?
