Octave's gunzip function is just a .m file.  It ultimately calls
another function called unpack to do the work.  I think the problem is
that gunzip is leaving it up to unpack to determine which
uncompression utility to use, when it should probably be forcing it to
use gzip.  It would be great if someone could have a look at this
problem and propose a patch.  Similar changes would likely be
appropriate for the bunzip2, untar, and unzip functions.
