	* sinfo.ads, sinfo.adb: Modify comment about adding fields to be more
	correct, and to be in a more convenient order.
	(Default_Storage_Pool): New field of N_Compilation_Unit_Aux, for
	recording the Default_Storage_Pool for a parent library unit.
	* einfo.ads (Etype): Document the case in which Etype can be Empty.
	* sem_prag.adb (Pragma_Default_Storage_Pool): Analyze the new
	Default_Storage_Pool pragma.
	* sem.ads (Save_Default_Storage_Pool): Save area for push/pop scopes.
	* gnat_ugn.texi: Document Default_Storage_Pool as a new configuration
	pragma.
	* freeze.adb (Freeze_Entity): When freezing an access type, take into
	account any Default_Storage_Pool pragma that applies. We have to do
	this at the freezing point, because up until that point, a Storage_Pool
	or Storage_Size clause could occur, which should override the
	Default_Storage_Pool.
	* par-prag.adb: Add this pragma to the list of pragmas handled entirely
	during semantics.
	* sem_ch8.adb (Push_Scope, Pop_Scope): Save and restore the
	Default_Storage_Pool information.
	* opt.ads (Default_Pool, Default_Pool_Config): New globals for recording
	currently-applicable Default_Storage_Pool pragmas.
	* opt.adb: Save/restore the globals as appropriate.
	* snames.ads-tmpl (Name_Default_Storage_Pool,
	Pragma_Default_Storage_Pool): New pragma name.

	* make.adb (Switches_Of): Put the spec and body suffix in canonical
	case.
