Probably because in fact there is no problem. License terms differs, but the Copyright notice says: "GNAT is free software; you can redistribute it and/or modify it under 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 similarly for previous GNAT versions under *GPLv2-or-later*. So if you have a mixture of GPLv2 and GPLv3 libraries with such copyright notices you can legally distribute the bundle under GPLv3 (or later) Just my 2c. -- Manuel Collado - http://lml.ls.fi.upm.es/~mcollado
