        * sem_res.adb (Resolve_Unary_Op): Add warning for use of unary minus
	with multiplying operator.
	(Expected_Type_Is_Any_Real): New function to determine from the Parent
	pointer whether the context expects "any real type".
	(Resolve_Arithmetic_Op): Do not give an error on calls to the
	universal_fixed "*" and "/" operators when they are used in a context
	that expects any real type. Also set the type of the node to
	Universal_Real in this case, because downstream processing requires it
	(mainly static expression evaluation).
	Reword some continuation messages
	Add some \\ sequences to continuation messages
	(Resolve_Call): Refine infinite recursion case. The test has been
	sharpened to eliminate some false positives.
	Check for Current_Task usage now includes entry barrier, and is now a
	warning, not an error.
	(Resolve): If the call is ambiguous, indicate whether an interpretation
	is an inherited operation.
	(Check_Aggr): When resolving aggregates, skip associations with a box,
	which are priori correct, and will be replaced by an actual default
	expression in the course of expansion.
	(Resolve_Type_Conversion): Add missing support for conversion from
	a class-wide interface to a tagged type. Minor code cleanup.
	(Valid_Tagged_Converion): Add support for abstact interface type
	conversions.
	(Resolve_Selected_Component): Call Generate_Reference here rather than
	during analysis, and use May_Be_Lvalue to distinguish read/write.
	(Valid_Array_Conversion): New procedure, abstracted from
	Valid_Conversion, to incorporate accessibility checks for arrays of
	anonymous access types.
	(Valid_Conversion): For a conversion to a numeric type occurring in an
	instance or inlined body, no need to check that the operand type is
	numeric, since this has been checked during analysis of the template.
	Remove legacy test for scope name Unchecked_Conversion.

	* sem_res.ads: Minor reformatting

	* a-except.adb, a-except-2005.adb: Turn off subprogram ordering
	(PE_Current_Task_In_Entry_Body): New exception code
	(SE_Restriction_Violation): Removed, not used

	* a-except.ads:  Update comments.

	* types.h, types.ads: Add definition for Validity_Check
	(PE_Current_Task_In_Entry_Body): New exception code
	(SE_Restriction_Violation): Removed, not used
