[adding gnulib, as this problem is really a gnulib one, not a coreutils]

The Austin group debated making the next version of POSIX required to
always return a non-NULL result for strerror (although for out-of-range
errors, there was no guarantee that the string had to be unique, as in
printing what the out-of-range value was). However, I think that proposal
has stalled, so the Interix behavior of returning NULL for strerror(-1) is
not yet non-POSIX compliant. I am very much in favor of a gnulib
implementation of strerror that works harder to provide non-NULL results.

Actually, gettext encourages putting %d in the translation, so that
languages that use pluralization rules in their translation can deal with
it better. In other words, Paul's suggested wording is better.
For reference, here's what cygwin does with unknown errors:
"Unknown error %u"
without translation (but then again, cygwin lacks builtin translation).
