72Version 3.1, 31 March 2009

74Copyright (C) 2009 <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.fsf.org">Free Software Foundation, Inc.</link>
75
76Everyone is permitted to copy and distribute verbatim copies of this
77license document, but changing it is not allowed.
78
79This GCC Runtime Library Exception ("Exception") is an additional
80permission under section 7 of the GNU General Public License, version
813 ("GPLv3"). It applies to a given file (the "Runtime Library") that
82bears a notice placed by the copyright holder of the file stating that
83the file is governed by GPLv3 along with this Exception.
84
85When you use GCC to compile a program, GCC may combine portions of
86certain GCC header files and runtime libraries with the compiled
87program. The purpose of this Exception is to allow compilation of
88non-GPL (including proprietary) programs to use, in this way, the
89header files and runtime libraries covered by this Exception.
90
910. Definitions.
92
93A file is an "Independent Module" if it either requires the Runtime
94Library for execution after a Compilation Process, or makes use of an
95interface provided by the Runtime Library, but is not otherwise based
96on the Runtime Library.
97
98"GCC" means a version of the GNU Compiler Collection, with or without
99modifications, governed by version 3 (or a specified later version) of
100the GNU General Public License (GPL) with the option of using any
101subsequent versions published by the FSF.
102
103"GPL-compatible Software" is software whose conditions of propagation,
104modification and use would permit combination with GCC in accord with
105the license of GCC.
106
107"Target Code" refers to output from any compiler for a real or virtual
108target processor architecture, in executable form or suitable for
109input to an assembler, loader, linker and/or execution
110phase. Notwithstanding that, Target Code does not include data in any
111format that is used as a compiler intermediate representation, or used
112for producing a compiler intermediate representation.
113
114The "Compilation Process" transforms code entirely represented in
115non-intermediate languages designed for human-written code, and/or in
116Java Virtual Machine byte code, into Target Code. Thus, for example,
117use of source code generators and preprocessors need not be considered
118part of the Compilation Process, since the Compilation Process can be
119understood as starting with the output of the generators or
120preprocessors.
121
122A Compilation Process is "Eligible" if it is done using GCC, alone or
123with other GPL-compatible software, or if it is done without using any
124work based on GCC. For example, using non-GPL-compatible Software to
125optimize any GCC intermediate representations would not qualify as an
126Eligible Compilation Process.
127
1281. Grant of Additional Permission.
129
130You have permission to propagate a work of Target Code formed by
131combining the Runtime Library with Independent Modules, even if such
132propagation would otherwise violate the terms of GPLv3, provided that
133all Target Code was generated by Eligible Compilation Processes. You
134may then convey such a combination under terms of your choice,
135consistent with the licensing of the Independent Modules.
136
1372. No Weakening of GCC Copyleft.
138
139The availability of this Exception does not imply any general
140presumption that third-party software is unaffected by the copyleft
141requirements of the license of GCC.

194	Everybody's got issues.  Even the C++ Standard Library.

196      <para>
197	The Library Working Group, or LWG, is the ISO subcommittee responsible
198	for making changes to the library.  They periodically publish an
199	Issues List containing problems and possible solutions.  As they reach
200	a consensus on proposed solutions, we often incorporate the solution.

203	Here are the issues which have resulted in code changes to the library.
204	The links are to the specific defect reports from a <emphasis>partial

206	at the <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.open-std.org/jtc1/sc22/wg21/">ISO C++
