	* g-debpoo.adb
	(Default_Alignment): Rename as Storage_Alignment. This is not
	a "default" that can be overriden. Augment comment to clarify
	intent and document why we need to manage alignment padding.
	(Header_Offset): Set to Header'Object_Size instead of 'Size
	rounded up to Storage_Alignment. Storage_Alignment on the
	allocation header is not required by our internals so was
	overkill. 'Object_Size is enough to ensure proper alignment
	of the header address when substracted from a storage address
	aligned on Storage_Alignment.
	(Minimum_Allocation): Rename as Extra_Allocation, conveying that
	this is always added on top of the incoming allocation requests.
	(Align): New function, to perform alignment rounding operations.
	(Allocate): Add comments on the Storage_Address computation
	scheme and adjust so that the alignment padding applies to that
	(Storage_Address) only.

	* exp_ch3.adb (Default_Initialize_Object): Remove incorrect

	* cstand.adb (Create_Standard): Use E_Array_Type for standard
	string types. Make sure index of Any_String/Any_Array is in a list.
	* errout.adb: Minor reformatting.
