[Vm-dev] [patch] SqueakVM doesn't build on OSS systems

[Igor Stasenko]

What kills me that why every application should care about knowing
what is the default sound device exists in system...
Why there is not API in system or OSS library, which could enumerate
available sound devices ,
or even take the one, preferred by user?
