I've done a little bit of playing around with gzip 1.2.4.  It works on
16 bit MS-DOS platforms with a bit of  tweaking, and I got all modules
to compile under 2.11BSD.  Unfortunately, I ended up  with a couple of
undefined references on linking, and I haven't had time  to look at it
in more detail.  On the whole, though, it looks as if it could be made
to work, maybe with a little tweaking.

Should be doable.
