From c817b9916f1134f687ba53220d607e6e193cf651 Mon Sep 17 00:00:00 2001
From: Martin Mares <mj@ucw.cz>
Date: Thu, 4 May 2000 20:18:46 +0000
Subject: Added --enable-ipv6 which tells configure to select the right
 configuration for IPv6 automatically.

Added --enable-warnings which turns off some more warnings.

Default protocol list now depends on --enable-ipv6.
