    `You may also combine or link a "work that uses the Library" to
    produce a work containing portions of the Library, and distribute
    that work under terms of your choice, provided that you give
    prominent notice with each copy of the work that the specified
    version of the Library is used in it, and that you include or
    provide public access to the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work. (i.e. If you make changes to the
    Library you must distribute those, but you do not need to
    distribute source or object code to those portions of the work
    not covered by this licence.)'

 any additional restriction, and so does not affect compatibility
 with the GNU General Public Licence (GPL). If you wish to negotiate
