From b0d4fa8b5f144cbe6f7f975e85bc963246bdc37f Mon Sep 17 00:00:00 2001
From: Kenneth R Westerback <krw@cvs.openbsd.org>
Date: Sat, 29 Mar 2003 02:34:18 +0000
Subject: Use sc_print_addr() where possible to improve messages.

Put debug messages in #ifdef sections.

Eliminate a less than useful error message.
