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.
