Well, I've signed a contract to write a native PDP-10 target. I just
hope my work will be useful.

Perhaps a bad idea, but how about something like defining bfd_byte
to be a short on an 8-bit-char host debugging a greater-than-8-bit-char
target? That way, the target memory could still be accessed as an
array of chars, though with some memory overhead.

Right. I will report back as soon as I have a more clear picture of
what needs to be done.
