I believe that we have long had agreement on making the relevant files
distprep targets, so this will not be an issue. Anyway, the whole
thing is a silly argument anyway: we can certainly make this
compatible back even as far as Perl 5.0 if need be for very little
extra work.

What is worth a little bit of effort to establish is exactly what
version of Perl we're already depending on, so that we can document
that for the benefit of future tool writers. There's no reason why
this particular thing needs to be compatible further back than what is
already required otherwise.
