--- Comment #2 from Joseph S. Myers <jsm28 at gcc dot gnu.org> 2011-02-22 16:33:34 UTC --- Joern, since the GFDL says: If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software. it ought not be controversial to add a statement that examples of code in the internals manual are also released under the GPL. I'd advise preparing a patch adding a statement to the effect that You can redistribute and/or modify examples of program code in this manual 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. and sending the patch to RMS for legal review as well as gcc-patches for technical review.
