PowerPC volatile interlocked

[Pierre d'Herbemont]

Hi!

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.
