Ah, thanks.  reality.sgi.com has the won't-frag disease, so I couldn't
easily check it myself.

Speaking of how things have changed...if I might be permitted a brief
moment of own-horn-blowing, my tar (when used correctly, of course)
does as well as possible against the Zwicky tests.  (By which I mean it
gets everything right except the dynamic tests, and produces reasonable
results for those - in particular, it doesn't break.  If you're not
using Berkeley-FFS filesystems (what SunOS calls 4.2, Solaris calls
ufs, NetBSD calls ffs, etc), it can't read the filesystem directly and
hence gets a few more tests wrong.)
