The source code was separate files, but the binary 'work as a whole'
had to be one.  I don't think DOS even had a concept of loading binary
libraries separate from the main executable.  And the binary obviously
is controlled by the copyright on the source.   So while I don't like
it, I can see the point that it does not meet the GPL requirement any
more than it would if it were linked to a commercial library that
another user would have to purchase.  And there's a reasonable chance
they could make an equivalent case even where shared libraries can be
used, since the intent is the same.

Yes, so, the only way to help keep others from being harmed by this is
to dual-license code so they can't possibly make such a claim.  It
doesn't happen with perl because Larry Wall understood that long ago.
Or, if you are so sure of your legal footing, distribute something
that they will challenge yourself and win the case that will set the
precedent for the rest of us.   But I'd guess dual-licensing would be
easier and cheaper.
