	* par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
	(P_Interface_Type_Definition): Remove the formal Is_Synchronized because
	there is no need to generate always a record_definition_node in case
	of synchronized interface types.
	(P_Type_Declaration): Update calls to P_Interface_Type_Definition.
	(P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
	illegal in Ada 95, in cases where it is legal. Change the warnings to
	errors in other cases. Don't give the error unless the "not null"
	parses properly. Correct the source position at which the error occurs.
	(P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
	P_Null_Exclusion, to suppress "not null" warnings.
	(P_Identifier_Declarations): Code cleanup. Removed unrequired label and
	associated goto statements.

	* par-endh.adb (Pop_End_Context): Allow more flexibility in placement
	of END RECORD

	* scans.ads (Type_Token_Location): New flag

	* par-ch6.adb (P_Mode): Check specifically for case of IN ACCESS
	(P_Formal_Part): Pass Allow_Anonymous_In_95 => True to
	P_Null_Exclusion, to suppress "not null" warnings.
