Re: [ZooLib-dev] Fixing an optimization problem in ZByteSwap.h (PowerPC)

Excellent. Thanks Richard. I've merged your changes here and will check 
them in shortly. I opted to handle the ZThreadTM.cpp problem by 
excising sTestAndSet altogether and just using ZAtomic_XXX -- I think 
sTestAndSet was just a hangover from ages ago that I'd forgotten about.

I've been curious about register r0, but have never dug around enough 
to understand what the behavior and restrictions are. In some code it 
seems that r0 is treated as being a zero constant, but that's clearly 
not always the case.

A+
