I'm following up on my own message here. I've been discussing it with
monks over at perlmonks (https://perlmonks.org) and someone there
(monk named choroba) knew what was wrong; the file
/usr/share/perl5/5.40/pods/perldiag.pod is, on Cygwin, not installed
automatically with the base perl executable, library and core modules.
It's in, rather, the optional package <<perl_pods>>.  So I installed
that package and the problem went away.
