Its broken in that compress is now definitely sub-optimal in
compression terms. It's also broken to the extent that someone (UNISYS
I think) claim to own the patent to the compress compression algorithm
and thus there has been an ongoing rumour for some time that compress
may get pulled from standard UNIX distributions etc.

If a move is made to gzip then I would assume that the Cambridge FTP
site would carry (a) the sources to gzip and (b) gzip compiled for the
standard systems that HOL is supported on (the gzip binary is only
about 70k anyway). If someone is going through the hassle of ftp-ing
HOL and setting up a system the the extra hassle of downloading a small
binary and sticking it in /usr/local/bin or where-ever seems fairly
trivial!
