From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libstdc++-v3/libsupc++/new | 114 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 114 insertions(+) create mode 100644 libstdc++-v3/libsupc++/new (limited to 'libstdc++-v3/libsupc++/new') diff --git a/libstdc++-v3/libsupc++/new b/libstdc++-v3/libsupc++/new new file mode 100644 index 000000000..80ee3ba0f --- /dev/null +++ b/libstdc++-v3/libsupc++/new @@ -0,0 +1,114 @@ +// The -*- C++ -*- dynamic memory management header. + +// Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, +// 2003, 2004, 2005, 2006, 2007, 2009, 2010 +// Free Software Foundation + +// This file is part of GCC. +// +// GCC 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 3, or (at your option) +// any later version. +// +// GCC 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.
