+ build an internal function to handle the displacement. If the actual
+ is null this function returns null because no displacement is
+ required; otherwise performs a type conversion that will be
+ expanded in the code that returns the value of the displaced actual.
+ (Expand_Interface_Actuals): Avoid the generation of unnecessary type
+ conversions that have no effect in the generated code because no
+ displacement is required. Code cleanup; use local variables to
+ avoid repeated calls to the subprogram directly_designated_type().
+
+ * exp_util.ads, exp_util.adb (Is_Predefined_Dispatching_Operation):

+ (Find_Interface_In_Descendant): Protect the frontend against

+ (Access_Definition): Reject ALL on anonymous access types.
+ (Build_Derived_Record_Type): In the case of Ada 2005, allow a tagged
