From 523f2003fa150b5b5619ad35392ed06dac933fa6 Mon Sep 17 00:00:00 2001
From: Robert James Kaes <rjkaes@users.sourceforge.net>

Subject: Removed the DNS API calls and replaced them with the standard
 gethostbyname() and gethostbyaddr() functions.  This is possible because
 tinyproxy now uses a standard pre-forked() method.
