From fb6b9b91d11dacb448979bb7770182f1731e9f99 Mon Sep 17 00:00:00 2001 From: "Pedro F. Giffuni" Date: Sat, 27 Jul 2013 19:57:20 +0000 Subject: Virgin import of patch-2.5.9, the last official GPLv2 release. As in previous imports we dropped the mkinstall and pc directories as they are of no use to us. Differently from previous imports, patch.1 was not renamed and is maintained with its original name (patch.man). If we ever merge this into the main tree, care must be taken to rename it back. --- rename.c | 112 --------------------------------------------------------------- 1 file changed, 112 deletions(-) delete mode 100644 rename.c (limited to 'rename.c') diff --git a/rename.c b/rename.c deleted file mode 100644 index d04a8bc0c8ec9..0000000000000 --- a/rename.c +++ /dev/null @@ -1,112 +0,0 @@ -/* BSD compatible rename and directory rename function for System V. - Copyright (C) 1988, 1990 Free Software Foundation, Inc. - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2, or (at your option) - any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
