	* sem.adb: Make sure predefined units are compiled with GNAT_Mode true
	when needed for proper processing of categorization stuff

	* sem_cat.adb:
	For several cases, make errors in preealborate units warnings,
	instead of errors, if GNAT_Mode is set. For AI-362.

	* sem_elab.adb (Check_Elab_Call): Call to non-static subprogram in
