we already require zip 3.0 for gbuild, which doesn't ship with MacOS X
(at least not with the versions that were current when i looked at this
problem early last year), so requiring a less outdated (2005? isn't
Apple supposed to ship only the most innovative products?) unzip sounds
fine to me.
i wonder, though, whether external build systems generally cope with
having the timestamps mangled: what happens when the Makefile.in happens
to end up with older timestamp than Makefile.am, would that kind of
thing trigger spurious rebuilds?
