	* sem_ch6.adb (Check_Limited_Return): Make global to package
	for use elsewhere.
	(Analyze_Expression_Function): Remove duplicated code, pre-analyze
	expression to capture names and call Check_Limited_Return so
	that semantic checks are identical to those for regular functions
	returning limited types.

	* bindgen.adb: Fix typo.
	* sem_ch6.adb: Minor reformatting.

	* s-os_lib.adb (Argument_String_To_List): fix handling of
	windows separators
