From 71eefcd38e76a7e57e1430c45324816de6bde9f0 Mon Sep 17 00:00:00 2001
From: Ton Voon <tonvoon@users.sourceforge.net>
Date: Thu, 23 Dec 2004 09:30:55 +0000
Subject: Another attempt at fixing check_http compile on Redhat EL3. Fixed
 check_icmp compile (Lynne Lawrence - 1087171) - still some code changes to
 check_icmp outstanding. Fixed compile of check_dhcp (complaining about
 socklen_t). Added acknowledgements for Coreutils and curl
