	* sem_ch13.adb (Rep_Item_Too_Late): Better error message for
	an illegal aspect that freezes the entity to which it applies.

	* a-stwibo.ads, a-stzbou.ads
	("="): Add overriding keyword before function to avoid crash when
	compiler is called with -gnatyO (check overriding indicators).

	* sem_prag.adb (Analyze_Pragma, case Check_Policy):  If this
	is a configuration pragma and it uses the ARG syntax, insert
	the rewritten pragma after the current one rather than using
	Insert_Actions.
