An interesting footnote: I've just downloaded the sources of GtkAda (GPL 
   Edition) from libre.adacore.com and it too contains the linking 
exception. But as has been discussed many times this alledgedly doesn't 
mean anything for the licence under which GtkAda (GPL Edition) is 
distributed.

Probably you have 3 choices: a) don't distribute under any licence other 
than GPL, b) ask a lawyer or c) do what you want an hope for the best.
