From a77fd8ed0a958b626101e71e57ce95a2c11355cb Mon Sep 17 00:00:00 2001
From: charnier <charnier@FreeBSD.org>
Date: Sun, 16 Jan 2005 10:49:48 +0000
Subject: Add prototypes and remove unused variables for WARNS=6 compliance.
 Add 'usage: ' in front of usage string. Use warnx(3) instead of fprintf in
 error messages to get progname prepended.
