Lots of us were certainly running 32 bit when we started developing OIIO, so if
there are non-64 bit breaks, it's probably a minor issue to fix. But I'm not
sure we ever compiled and tested for PPC.
Probably not.
Given the that PowerPC is now on the decline, I won't pursue this and
look for other alternative.
However, looking at wikipedia (I am no CPU expert), it says that PPC and
ARM are both bi-endian.
If we have problem with PPC and given ARM's rising popularity, this
problem may (not sure about hardware opcode and endian settings) resurface.
Thanks for the feedback.
I will not pursue this for now.
