Adding the gcc runtime library exception, which is needed for >=gcc-4.4

3     Version 3.1, 31 March 2009
5     Copyright (C) 2009 Free Software Foundation, Inc. <http://fsf.org/>
7     Everyone is permitted to copy and distribute verbatim copies of this
8     license document, but changing it is not allowed.
10     This GCC Runtime Library Exception ("Exception") is an additional
11     permission under section 7 of the GNU General Public License, version
12     3 ("GPLv3"). It applies to a given file (the "Runtime Library") that
13     bears a notice placed by the copyright holder of the file stating that
14     the file is governed by GPLv3 along with this Exception.
16     When you use GCC to compile a program, GCC may combine portions of
17     certain GCC header files and runtime libraries with the compiled
18     program. The purpose of this Exception is to allow compilation of
19     non-GPL (including proprietary) programs to use, in this way, the
20     header files and runtime libraries covered by this Exception.
22     0. Definitions.
24     A file is an "Independent Module" if it either requires the Runtime
25     Library for execution after a Compilation Process, or makes use of an
26     interface provided by the Runtime Library, but is not otherwise based
27     on the Runtime Library.
29     "GCC" means a version of the GNU Compiler Collection, with or without
30     modifications, governed by version 3 (or a specified later version) of
31     the GNU General Public License (GPL) with the option of using any
32     subsequent versions published by the FSF.
34     "GPL-compatible Software" is software whose conditions of propagation,
35     modification and use would permit combination with GCC in accord with
36     the license of GCC.
38     "Target Code" refers to output from any compiler for a real or virtual
39     target processor architecture, in executable form or suitable for
40     input to an assembler, loader, linker and/or execution
41     phase. Notwithstanding that, Target Code does not include data in any
42     format that is used as a compiler intermediate representation, or used
43     for producing a compiler intermediate representation.
45     The "Compilation Process" transforms code entirely represented in
46     non-intermediate languages designed for human-written code, and/or in
47     Java Virtual Machine byte code, into Target Code. Thus, for example,
48     use of source code generators and preprocessors need not be considered
49     part of the Compilation Process, since the Compilation Process can be
50     understood as starting with the output of the generators or
51     preprocessors.
53     A Compilation Process is "Eligible" if it is done using GCC, alone or
54     with other GPL-compatible software, or if it is done without using any
55     work based on GCC. For example, using non-GPL-compatible Software to
56     optimize any GCC intermediate representations would not qualify as an
57     Eligible Compilation Process.
59     1. Grant of Additional Permission.
61     You have permission to propagate a work of Target Code formed by
62     combining the Runtime Library with Independent Modules, even if such
63     propagation would otherwise violate the terms of GPLv3, provided that
64     all Target Code was generated by Eligible Compilation Processes. You
65     may then convey such a combination under terms of your choice,
66     consistent with the licensing of the Independent Modules.
68     2. No Weakening of GCC Copyleft.
70     The availability of this Exception does not imply any general
71     presumption that third-party software is unaffected by the copyleft
72     requirements of the license of GCC.
