strerror[_r]() only handles the messages that map to errno values.  And
if you use sockets, gnulib already maps quite a few windows errors to
errno values.

If you care about windows errors that do not map to errno values, you
are probably writing a windows-specific program, at which point gnulib
isn't going to help you.

If the underlying strerror_r translates, then yes, we have a mismatch
where some, but not all, errno values are translated to the user's
locale.  But this question was already asked last week:
http://lists.gnu.org/archive/html/bug-gnulib/2011-05/msg00421.html

and if someone does the work, we could certainly support translating the
gnulib-added errno values as well.
