Based on what I have read so  far, I think it may be best to stick with the
strerror() since that appears to be the way some of the other developers are
going (based primarily on MKS's website)

http://www.mkssoftware.com/docs/man5/sys_errlist.5.asp

The reason is that no strings related to Win32 error codes are provided in
this model while strerror() does (hence the reset by peer, which is a
standard windows networking error).  If we did have Cygwin support sys_errlist,
then it should somehow incorporate strerror().  That is probably not going to
be simple or easy.
