+	* exp_util.adb: Add with_clause for Freeze.
+	(Expand_Sliding_Conversion): New procedure for applying a
+	sliding subtype conversion to an array object of a
+	fixed-lower-bound subtype when needed.  It traverses the indexes
+	of the unconstrained array type/subtype to create a target

+	* sem_attr.adb (Attribute_Has_Access_Values): Pass

+	(Check_Choices.Check_Composite_Case_Selector): New procedure for
+	semantic checking of non-discrete case selectors.
+	(Check_Choices): If extensions are allowed then a non-discrete

+	* par-ch4.adb (P_Record_Or_Array_Component_Association): When
+	parsing a component association, check for both new syntax forms
+	used to specify a bound value in a case-choice aggregate.  In
+	the case of a box value, an identifier may occur within the box,
+	as in "Foo => <Abc>" instead of "Foo => <>". In the more general
+	case, an expression (or a box) may be followed by "is
