Good point. Will do in a subsequent patch.

Just so you know, I wrote patches to fully implement CD audio support,
but they only work on Mac OS X < 10.4. Because Wine lists 10.4 as the
minimum required version for Mac OS, I decided not to send them.

I think we'll end up doing something like that. But you'll have to ask
Alexandre about the drive issue. That's beyond me too at the moment.

Actually, Windows XP (at least) also presents audio CDs as volumes. And
the audio CD IOCTLs are deprecated on Vista and up. So I think that, in
the future, we may end up doing the same on Linux, too.

Thanks for the advice on the ERR message. And good luck with MCICDA.
