2007-12-06  Robert Dewar  <dewar@adacore.com>

	* inline.adb (Back_End_Cannot_Inline): Use new flag
	Has_Pragma_Inline_Always instead of obsolete function Is_Always_Inlined

	* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Use new flag
	Has_Pragma_Inline_Always instead.
	of obsolete function Is_Always_Inlined
	(Build_Body_To_Inline): Same change
	(Cannot_Inline): Same change
	Do not give warning on exception raise in No_Return function

	* sem_ch13.adb (Analyze_Record_Representation_Clause): If an inherited
	component has two inconsistent component clauses in the same record
	representation clause, favor the message that complains about
	duplication rather than inconsistency.
	Update comments.
	(Record_Representation_Clause): Do not warn on missing component
	clauses for inherited components of a type extension.
	(Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
	an overloadable item if it is a pragma that can apply to multiple
	overloadable entities (e.g. Inline) because a pragma cannot be on
	more than one chain at a time.
	(Validate_Unchecked_Conversion): Add code to warn on unchecked
	conversion where one of the operands is Ada.Calendar.Time.
	(Analyze_Attribute_Definition_Clause): Fix typo in error message.
	For now, ignore Component_Size clause on VM targets, as done for
	pragma Pack.
