Hi!, I've found this clause at the end of a license header:
* As a special exception, you may use this file as part of a free * software library without restriction. Specifically, if other files * instantiate templates or use macros or inline functions from this * file, or you compile this file and link it with other files to * produce an executable, this file does not by itself cause the * resulting executable to be covered by the GNU General Public * License. This exception does not however invalidate any other * reasons why the executable file might be covered by the GNU General * Public License. It is part of this submission: https://savannah.gnu.org/task/?13049 Is there any problem on approving it?
