True ;) .. but that's why the API needs to be defined and standardised.
On PowerPC it returns 32 (or 64), and the x86 version returns 2 values, the
position, and also a bool telling you if it was zero or not (useful for loop
termination)
I think all hardware that I've seen is easy to factor into the win32
intrinsic api.
