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. --- getopt.h | 123 +++++++++++++++++++++++++++++++++++++++++++-------------------- 1 file changed, 85 insertions(+), 38 deletions(-) (limited to 'getopt.h') diff --git a/getopt.h b/getopt.h index 69256fd38647..4d6adeea0d68 100644 --- a/getopt.h +++ b/getopt.h @@ -1,26 +1,37 @@ /* Declarations for getopt. - Copyright (C) 1989,90,91,92,93,94,96,97 Free Software Foundation, Inc. + Copyright (C) 1989-1994, 1996-1999, 2001 Free Software Foundation, Inc. + This file is part of the GNU C Library. -NOTE: The canonical source of this file is maintained with the GNU C Library. -Bugs can be reported to bug-glibc@prep.ai.mit.edu. + 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 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.
