On a 64-bit machine, a 32-bit VM has to use the appropriate runtime
libraries. If you build a 32-bit VM on a 64-bit system, you have to link
to the right libraries. Google "linux 64-bit 32-bit" for the annoying
details. This is really not a big deal, but who wants to figure out that
kind of stuff, especially if you are building your own VM and you are
already running on a perfectly good 64-bit machine.
Hmmm, even more especially if you are building an application that is
supposed to be portable across a wide variety of target machines. It
works on RISC OS, but not on AMD64? Go figure.
