From a79dc754b8d7ef103a908305e1494515b192ccdc Mon Sep 17 00:00:00 2001
From: Thomas Radke <tradke@aei.mpg.de>
Date: Sat, 28 Oct 2000 13:59:32 -0500
Subject: [svn-r2747] Purpose:     Detect whether the system has the
 netinet/tcp.h header file. Description:     The Stream VFD uses setsockopt(2)
 to set TCP_NODELAY on an opened     socket. This constant is defined normally
 in netinet/tcp.h     except for GNU cc under Windows where this header
 doesn't exist. Platforms tested:     Windows NT, GNU cc
