You're right, and not right. Best thing to do would be adding all the
??dMessage's to mmddk.h, then fix what breaks, and make whole winmm 64
bits safe, THEN it would be useful to make mixer 64 bits safe, I changed
it to be future compatible though, wine doesn't build for 64 bits now
anyway so there's no harm in making this code 64 bits safe in advance,
so I'll send a try 3.
