Re: getsockopt broken in cygwin 1.3.6-1

I experienced the same problem with getsockopt() in the distributed
squid package.  I tracked down the problem to a little typo in
winsup/cygwin/net.cc.  I've included a patch that fixes the problem.

This is the first time I've contributed anything to cygwin.  I've read
the web pages and I think I've included everything required.  Please let
me know if I've done this incorrectly.
