According to http://www.sockets.com/a_c2.htm (and a few other sources),
meaningful winsock error information cannot be obtained from errno;
WSAGetLastError() should be used instead.  In this situation,
rb_sys_fail won't work.

If I actually had a compiler installed on Windows, I'd write a patch,
but this should be an easy fix anyway.

This explains why the code was failing with such a strange error
message; I wonder why it was failing in the first place, though.
