	* sprint.adb (Sprint_Node_Actual, case Parameter_Specification): Do not
	print null exclusion twice in the case of an access definition,
	Implement new -gnatL switch
	Remove N_Return_Object_Declaration. We now use
	N_Object_Declaration instead. Implement the case for
	N_Extended_Return_Statement. Alphabetize the cases.
	Add cases for new nodes N_Extended_Return_Statement and
	N_Return_Object_Declaration. The code is not yet written.
	Update the output for N_Formal_Object_Declaration
	and N_Object_Renaming_Declaration.
	(Write_Itype): Account for the case of a modular integer subtype whose
	base type is private.
