From d54f92ab0d3ef489acae67a35e155470499cc0be Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>
Date: Sun, 3 Jul 2005 07:17:12 +0000
Subject: [PATCH] Include fd-reopen.h. Include stdio--.h, not stdio-safer.h.
 (input_desc): Remove.  All uses changed to STDIN_FILENO. (set_input_file):
 Reopen stdin, to simplify code. (create_output_file): Use fopen, not
 fopen_safer.
