	* s-os_lib.ads, s-os_lib.adb(Normalize_Pathname): Support the case of
	an unresolved Directory argument, by recursively resolving it
	against the current dir.

	* sem_ch6.adb (Process_Formals): A function declaration that
	returns a class-wide type must have freeing deferred, so that it
	is not frozen before the class-wide type and its root type are
	frozen. This is significant when there may be a limited view of
	the class_wide type in another package.
