I went with 5.8 as the cutoff, for a couple of reasons: we're not in
the business of telling people they ought to be up-to-date, but only of
rejecting versions that demonstrably fail badly; and I found out that
older versions of awk are not sufficiently competent with && and || to
code a more complex test properly :-(. A version check that doesn't
actually do what it claims to is worse than useless, and old buggy awk
is exactly what you'd expect to find on a box with old buggy perl.
(It's also worth noting that the perl version seen at configure time
is not necessarily that seen at runtime, anyway, so there's not a lot
of point in getting too finicky here.)
