One "minor" problem is to get gcc to cope with that. There's a very old gcc
port (2.95 era), I'm not sure how complete that is. At that time gcc had
machinery in it for dealing with machines whose byte is not 8 bits, and/or that
are not byte addressable. The former is gone now, and the latter may also be.
(Maybe not; there might still be DSP-type gcc targets that use it.) It doesn't
seem horribly difficult to resurrect it, though.
