Hmm. No, the problem appears to be that none of the symbols
defined by the unit are actually used in the 5.001m sources.
Those symbols are:

VAL_O_NONBLOCK, VAL_EAGAIN, RD_NODATA, EOF_NONBLOCK

Was there a patch to POSIX.xs or FCNTL.xs or something I was supposed to
apply that used those symbols, or was I supposed to fake it and insert
the unit anyway for future use by extensions? I didn't deliberately
exclude it; I just didn't remember to explicitly do anything to include it.

I'm making no promises about any hypothetical "next time". :-)

ReadKey might use them, but currently doesn't (probably because I just
haven't gotten around to it). And ReadKey isn't part of the dist anyhow.

Andy, I think you'll just have to force inclusion of this Unit. Or, for
that matter, if perl is going to be the local Configure repository, it
might make sense to set up a .PL or .SH file in the dist that exists
solely to name symbols and to pull in Units.

I think that is correct Andy.

The non-blocking stuff isn't used in anything that is part of 5.001m.
It is for use in some of the existing external modules - source
filters, Tk and ReadLine (I think).
