From fb6209a30fd576cd740eefe0a3ad88d65d2bb2b7 Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Tue, 29 Jan 2008 13:32:07 +0000
Subject: Give preference to iptables header files

Have the header files in the iptables source tree take precedence
over those from the kernel source. Otherwise, building the current
iptables from subversion just fails with kernels < 2.6.25.
