--  This version of Ada.Exceptions is a simplified version for use in
--  AVR-Ada.  It supports simplified exception handling without
--  exception propagation, i.e. restriction No_Exception_Propagation
--  is set.
--
--  You also have to define __gnat_last_chance_handler somewhere in
--  your code as the typical binder generated last-chance-handler is
--  stripped in AVR-Ada.
