From 82c790f916d0e107de65511b0c9a912ed613d3c1 Mon Sep 17 00:00:00 2001
From: dwmalone <dwmalone@FreeBSD.org>
Date: Tue, 29 Jun 2004 21:28:09 +0000
Subject: 1) ANSIfy. 2) Use %p to print a pointer. 3) Use longs for fileids and
 ino to avoid comparing signed and unsigned. 4) Make the KVM_READ macro a
 little more cranky. 5) Set WARNS while I'm here.
