From 3d436f88efb20e72498d5756aa0720c494689e65 Mon Sep 17 00:00:00 2001
From: Greg Stein <gstein@apache.org>
Date: Sun, 3 Feb 2002 13:39:47 +0000
Subject: Provide more outputs for the apr-config file. Corrected some handling
 of the prefix, and the exit code for the --help switch.

Make the chmod +x for apr-config part of the "config commands" so that
it will occur every time that config.status is run.
