------- Additional Comments From dank@kegel.com 2007-22-04 16:34 ------- I've looked, but I haven't found a document defining who is allowed to change the FS register. (Presumably it's part of the i686 linux ABI.)
This is something that needs to be raised at every Linux conference until it is resolved. Wine can't resolve this on its own.
