Add Mingw-w64 licenses and version
This patch adds several license files pertinent to the runtime DLLs that are part of the Mingw-w64 project, specifically: * COPYING3.GCC - GPL v3 - applies to libstdc++ and libgcc * COPYING.RUNTIME - GCC Runtime library exception - applies to libstdc++ and libgcc * COPYING.MinGW-w64-runtime.txt - applies to libstdc++, libgcc and libwinpthread These licenses are included in the binary distribution when the corresponding DLLs are included in the distribution. Also this patch adds Mingw-w64 version information to VERSION.txt when compiling with Mingw-w64.

On Windows the toolchain also uses several DLLs that are part of the Mingw-w64

212+
It sounds vague, but as to be found at
213+
<http://lists.debian.org/debian-legal/2004/12/msg00295.html>, it gives an
214+
impression that the author could be willing to give an explicit
215+
permission to distribute those files e.g. under a BSD style license. So
216+
probably there is no problem here, although it could be good to get a
217+
permission from the author and then add a license into the Cephes files
218+
in MinGW runtime. At least on follow-up it is marked that debian sees the
219+
version a-like BSD one. As MinGW.org (where those cephes parts are coming
220+
from) distributes them now over 6 years, it should be fine.

GCC RUNTIME LIBRARY EXCEPTION
2+
3+
Version 3.1, 31 March 2009
4+
5+
Copyright (C) 2009 Free Software Foundation, Inc. <http://fsf.org/>
6+
7+
Everyone is permitted to copy and distribute verbatim copies of this
8+
license document, but changing it is not allowed.
9+
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.
15+
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.
21+
22+
0. Definitions.
23+
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.
28+
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.
33+
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.
37+
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.
44+
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.
52+
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.
58+
59+
1. Grant of Additional Permission.
60+
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.
67+
68+
2. No Weakening of GCC Copyleft.
69+
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.
