[comp.emacs] Compress/decompress

Adrian Clark writes he's having problems with these on VMS.
I've been using Martin Minow's LZCMP and LZDCM on VMS for a while
and have been entirely successful with them with tar.Z files pulled\
off prep. There are a few caveats:
1. Be sure you have fairly current versions (see Spring '88 VAX SIG
tapes for these if needed).
2. Use -b switch on LZDCM from unix based files; then Sid Penstone's
TAR reader will pull 'em all apart perfectly.

If running VMS 5.0, you MUST get the newest LZCMP/LZDCM; the old ones
will (I'm told) flat out fail. Problem is a realloc() on something
that was just a static array originally. This happens for the
usual VMS conditionalizations of Martin's sources, not in all
possible builds. It should be easy to fix, but since the latest
sources ARE available, it seems more reasonable to run those. I've
still got VMS 4.7 running here and find the old .EXE modules run
just fine. Read the comments in the src for HOW to run it. Operational
mistakes are the usual problems. I don't think lzcmp or lzdcm are
used exactly like compress/decompress must be under Unix.
