Of course, I forgot to mention that.  And it is true that my tarballs
compressed with bzip2 can't be restored on my 1994 Slackware 3.0 machine,
but I could compress with gzip (or even plain old compress) and I would be
able to restore them on good old linux 1.2.14.  And I'm reasonably certain
that something zipped on WinXP can be unzipped on Win3.1 (though I don't
know for sure).
