I think that it was Will Partain that described the problem as though one
had to do some assembly local to the CPU in order to get put the munging
through (perhaps I misunderstood it). -- So even if Apple's gcc accepted
asm, there would some (hard) work to do, in figuring out how the PPC (G3 &
G4) assmebly worked.
