	adjust the description.
	(Analyze_Attribute_Definition_Clause): In the case
	of an address, move up the code creating an entry in the table of
	address clauses.  Also create an entry for an absolute address.
	(Validate_Address_Clauses): Issue the warning for absolute
	addresses here too.  Tweak condition associated with overlays
	for consistency.

	the worst case.
