When gcc has its optimisation turned on, we should to specify __volatile__ for inline-ed assembler code. Without this patch you can't open an SaveDialog box on darwin/ppc, and probably can't do a lot of other things which needs InterlockedIncrement().
ChangeLog: - Make the PowerPC interlocked assembler code volatile.
