[Fedora-legal-list] GPLv2 with exception linked with GPLv3+

[Laurent Rineau]

The openscad package from Fedora has the following COPYING file:

========================quote==============================
==============
*********************************************************************
  As a special exception, you have permission to link this program
  with the CGAL library and distribute executables, as long as you
  follow the requirements of the GNU GPL in regard to all of the
  software in the executable aside from CGAL.
*********************************************************************
 
                    GNU GENERAL PUBLIC LICENSE
                       Version 2, June 1991
========================end 
quote=========================================
[and then there the text of GPLv2].

(from /usr/share/doc/openscad-2013.01.17/COPYING on Fedora 17).

The license of CGAL libraries is LGPLv3+ for some parts, and GPLv3+ for other parts. OpenSCAD 
does use the parts that are under GPLv3+.


Is the exception to GPLv2+, in the license of OpenSCAD, sufficient to make it compatible with 
the terms of the license GPLv3+? I am unsure of that.
