The whole point is that you can run a 64-bit VM on 32-bit hardware
provided your compiler has a 64-bit integer type (long long or
whatever). I made pre-compiled 64-bit VMs available for Pentium and
(32-bit native) PowerPC, neither of which are 64-bit hardware.

Not necessary. Execute 'ObjectMemory initBytesPerWord: 8', regenerate,
[ recompile, fix errors, run 64-bit VM ] repeatAsNecessary.

That's what we need. With appending '32' and '64' to the path so that
each version of the VM goes into a different tree. But it's no real
hassle to re-accept the path I guess, since it's mainly once per VM
release that most people who care will be wanting to generate both at
the same time...
