As Dave Haynie pointed out some time ago this is because the standard fast
ram on the A3000 lies in the $07000000-$07ffffff range, i.e., you would
need an address space of at least 128M---but even that would not be
sufficient in the long run, since further expansion memory may go up to
$7fffffff, i.e, 2G.  So, GNU Emacs will not be properly programmed for the
Amiga before it uses full 32 bit addressing (why use bit 31 for anything
but an address?).  Does anyone know how difficult this would be to implement?
