From: sos AT buggy DOT prospect DOT com DOT ru (Sergey Okhapkin)
Subject: net.cc patch
1 Mar 1998 03:10:15 -0800
Message-ID: <01BD451B.743732D0.cygnus.cygwin32.developers@sos>
To: "'cygwin32-developers AT cygnus DOT com'" <cygwin32-developers AT cygnus DOT com>

When using MS winsock proxy server (both v1.0 and v2.0), connect() call 
fails on duplicated socket handle (at least on Windows NT). This patch 
fixes the problem.

net.cc:	(DuplicateSocket): new static function, return original socket on 
Windows NT
		and duplicated one on Windows 95.
		Rest of the file - call it instead of DuplicateHandle.
