	* sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
	that relates operations of the parent type to the operations of
	the derived type has three distinct sources:
	a) explicit operations of the derived type carry an
	Overridden_Operation that designates the operation in the
	ancestor.
	b) Implicit operations that are inherited by the derived type
	carry an alias that may be an explicit subprogram (in which case
	it may have an Overridden_ Operation indicator) or may also be
	inherited and carry its own alias.
	c) If the parent type is an interface, the operation of the
	derived type does not override, but the interface operation
	indicates the operation that implements it.
	* sem_prag.adb: Minor reformatting.
	* sem_prag.adb (Check_External_Property): Update
	the comment on usage. Reimplement.

	* exp_ch5.adb (Expand_Assignment_Statement): In restricted
	profiles such as ZFP, ceiling priority is not available.

	* namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.

	* sem_elab.adb (Output_Calls): Use
	Get_Name_String, to clearly indicate that the global Name_Buffer
	is being used. The previous code used Is_Internal_Name, which
	returns a Boolean, but also has a side effect of setting the
	Name_Buffer. Then it called the other Is_Internal_Name, which uses
	the Name_Buffer for its input. And then it called Error_Msg_N,
	again using the Name_Buffer. We haven't eliminated the global
	usage here, but we've made it a bit clearer.
	This also allows us to have a side-effect-free version of
	Is_Internal_Name.
	* namet.ads, namet.adb: Provide a type Bounded_String, along with
	routines that can be used without using global variables. Provide
	Global_Name_Buffer so existing code can continue to use the
	global. Mark the routines that use globals as obsolete.  New code
	shouldn't call the obsolete ones, and we should clean up existing
	code from time to time.
	Name_Find_Str is renamed as Name_Find.
	* namet.h: Changed as necessary to interface to the new version
	of Namet.
	* bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
	Name_Find.
