Hope that's okay)

Good. It wasn't supposed to be that hard... :-)

Okay, I think I know what this is. If you check the documentation (the README is
available from http://cygutils.netpedia.net/perl/README.cygwin32-v1.4.1) and
search for io_sock.t, you'll find that there was a problem with it. We hacked the
test so that the build would go smoothly, since without this hack, the make test
/ perl harness *hangs* rather than reporting a failure. Unfortunately, this means
that there is no warning to the unsuspecting user that io_sock doesn't work
properly, unless you read the documentation pretty thoroughly.

The problem is that "fork"s don't work with dlls in cygwin. Yet. See the recent
thread "B20.1: Fork bug (Win95)" and an older thread "fork + dlls". Hopefully
this bug, which is a cygwin problem and not a perl problem, will be fixed in B21.

I don't understand this. But that's just because I'm (a) not a programmer, and
(b) a verifiable, card-carrying Perl newbie. How I ended up "maintaining" the
cygwin port of perl, I'll never figure out. I guess it's just because I'm good at
collecting other people's work and packaging it up nicely. :-)
