	* a-ststio.ads: Add pragma Preelaborate, per AI05-0283.
	* i-cstrea.ads (max_path_len): Change from variable to deferred
	constant to allow it to be used as a bound in string component
	in type System.File_IO.Temp_File_Record.
	* s-os_lib.ads, s-commun.ads, s-ficobl.ads, s-fileio.ads: Add pragma
	Preelaborate.
	* s-fileio.adb (Get_Case_Sensitive): Move function inside
	procedure Open.
	(File_Names_Case_Sensitive): Move variable inside
	procedure Open, to avoid violation of Preelaborate restriction
	(due to call to Get_Case_Sensitive).

	* layout.adb (Set_Elem_Alignment): Protect against meaningless
	size clause, to prevent overflow in internal computation of
	alignment.
