No roadblock, but more bugs uncovered and fixed.
And now huge is working.

These have all been cleaned up and all work now.

a.out is perfectly fine for MSDOS programming,
with the caveat that you must use complete
addresses, or offsets, and not attempt to
extract just the segment. There's not a lot of
code that tries to use "seg", and it is not
necessary to use it in anything I have seen.
