	* exp_ch7.adb, g-comlin.adb: Minor reformatting.

	* exp_ch4.adb (Expand_Allocator_Expression): Look through
	derived subprograms in checking for presence of an
	Extra_Accessibility_Of_Result formal parameter.
	* exp_ch6.adb (Expand_Call): Look through derived subprograms in
	checking for presence of an Extra_Accessibility_Of_Result formal
	parameter.
	(Expand_Call.Add_Actual_Parameter): Fix a bug in the
	case where the Parameter_Associatiations attribute is already set,
	but set to an empty list.
	(Needs_Result_Accessibility_Level):
	Unconditionally return False. This is a temporary
	change, disabling the Extra_Accessibility_Of_Result
	mechanism.
	(Expand_Simple_Function_Return): Check for
	Extra_Accessibility_Of_Result parameter's presence instead of
	testing Ada_Version when generating a runtime accessibility
	check which makes use of the parameter.
