I used gcc 3.4.6 bootstrapped as normal ('make bootstrap; make install')
on a 64-bit machine. If it is qemu generating bad code due to variations
in gcc behaviour, that's another argument in favour of scrapping the gcc
3.X based backend and using a self contained, handwritten insn selector
and register allocator.
