[Savannah-hackers-public] Clause in a license header

[Joan Lledó]

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?
