 "If the program uses fork and exec to invoke plug-ins, then the
 plug-ins are separate programs, so the license for the main program
 makes no requirements for them."

 libobjc contains an exception

 /* As a special exception, if you link this library with files compiled with
   GCC to produce an executable, this does not 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.  */
