I don't see any direct references to sys_errlist. The references to
sys_nerr are necessary to avoid coredump with an out-of-range errno
value --- at least on machines where strerror() is a macro that expands
to an unchecked array access.

I think the obvious fix is to supply a sys_nerr value on Cygwin.
