+	* contracts.ads: Update comment for Add_Contract_To_Item because
+	types can have contracts.  Follow (questionable) precedent and
+	declare new routine Analyze_Type_Contract as visible (following

+	* einfo.adb (Contract, Set_Contract): Id argument can be a type;

+	(Write_Field34_Name): Field name is "contract" for a type.
+	* einfo.ads: Update comment describing Contract attribute.
+	* sem_ch3.adb (Build_Derived_Numeric_Type): Is_Volatile should

+	(Check_Volatility_Compatibility): New procedure intended for use
+	in checking all SPARK legality rules of the form "<> shall be
+	compatible with respect to volatility with <>".
+	(Has_Enabled_Property): Update comment because Item_Id can be a
+	type.  Change name of nested Variable_Has_Enabled_Property
+	function to Type_Or_Variable_Has_Enabled_Property; add a
