From 34ead71a13152314bf149fbd185cd29b89ae5cb0 Mon Sep 17 00:00:00 2001
From: Karl Heuer <kwzh@gnu.org>
Date: Sun, 7 Jul 1996 22:36:38 +0000
Subject: [PATCH] (Fcopy_file): Use st_ino under DJGPP v2 and later to prevent
 copying file into itself. (check_executable): DJGPP v2 `stat' doesn't need to
 be augmented in case of executable files. (Ffile_modes): Use `stat' results
 as is in DJGPP v2 and later.
