From 1331cca1fa131d066afd0de5f2972061a520f3f0 Mon Sep 17 00:00:00 2001
From: Roland McGrath <roland@redhat.com>
Date: Fri, 24 Mar 1995 05:56:41 +0000
Subject: (handle_non_switch_argument): New function, broken out of
 decode_switches. (decode_switches): Set optind to 0 to reinitialize getopt,
 not to 1.  When getopt_long returns EOF, break the loop and handle remaining
 args with a simple second loop.
