It applies to a given file (the "Runtime Library") that<br /> 27bears a notice placed by the copyright holder of the file stating that<br /> 28the file is governed by GPLv3 along with this Exception.<br /> 29<br /> 30When you use GCC to compile a program, GCC may combine portions of<br /> 31certain GCC header files and runtime libraries with the compiled<br /> 32program. The purpose of this Exception is to allow compilation of<br /> 33non-GPL (including proprietary) programs to use, in this way, the<br /> 34header files and runtime libraries covered by this Exception.<br /> 35<br /> 360. Definitions.<br /> 37<br /> 38A file is an "Independent Module" if it either requires the Runtime<br /> 39Library for execution after a Compilation Process, or makes use of an<br /> 40interface provided by the Runtime Library, but is not otherwise based<br /> 41on the Runtime Library.<br /> 42<br /> 43"GCC" means a version of the GNU Compiler Collection, with or without<br /> 44modifications, governed by version 3 (or a specified later version) of<br /> 45the GNU General Public License (GPL) with the option of using any<br /> 46subsequent versions published by the FSF.<br /> 47<br /> 48"GPL-compatible Software" is software whose conditions of propagation,<br /> 49modification and use would permit combination with GCC in accord with<br /> 50the license of GCC.<br /> 51<br /> 52"Target Code" refers to output from any compiler for a real or virtual<br /> 53target processor architecture, in executable form or suitable for<br /> 54input to an assembler, loader, linker and/or execution<br /> 55phase. Notwithstanding that, Target Code does not include data in any<br /> 56format that is used as a compiler intermediate representation, or used<br /> 57for producing a compiler intermediate representation.<br /> 58<br /> 59The "Compilation Process" transforms code entirely represented in<br /> 60non-intermediate languages designed for human-written code, and/or in<br /> 61Java Virtual Machine byte code, into Target Code. Thus, for example,<br /> 62use of source code generators and preprocessors need not be considered<br /> 63part of the Compilation Process, since the Compilation Process can be<br /> 64understood as starting with the output of the generators or<br /> 65preprocessors.<br /> 66<br /> 67A Compilation Process is "Eligible" if it is done using GCC, alone or<br /> 68with other GPL-compatible software, or if it is done without using any<br /> 69work based on GCC. For example, using non-GPL-compatible Software to<br /> 70optimize any GCC intermediate representations would not qualify as an<br /> 71Eligible Compilation Process.<br /> 72<br /> 731. Grant of Additional Permission.<br /> 74<br /> 75You have permission to propagate a work of Target Code formed by<br /> 76combining the Runtime Library with Independent Modules, even if such<br /> 77propagation would otherwise violate the terms of GPLv3, provided that<br /> 78all Target Code was generated by Eligible Compilation Processes. You<br /> 79may then convey such a combination under terms of your choice,<br /> 80consistent with the licensing of the Independent Modules.<br /> 81<br /> 822. No Weakening of GCC Copyleft.<br /> 83<br /> 84The availability of this Exception does not imply any general<br /> 85presumption that third-party software is unaffected by the copyleft<br /> 86requirements of the license of GCC.<br /> 87 </p></div><p> 88 Hopefully that text is self-explanatory.
