        insert the renaming in front of the aspect's associated entity
        declaration rather than in front of the corresponding attribute

        of the interface operation is obtained from the ultimate alias
        of the interface primitive parameter, because that may be in

        a non-generic ancestor of the generic that is also an ancestor

        * exp_util.adb (Corresponding_Runtime_Package): Remove the condition
        related to No_Dynamic_Attachment which was wrong. Protected types
        with interrupt handlers (when not using a restricted profile)
        are always treated as protected types with entries, regardless
        of the No_Dynamic_Attachment restriction.
        * exp_ch9.adb (Expand_N_Protected_Type_Declaration): Simplify the code
        using the result of Corresponding_Runtime_Package.
        (Install_Private_Data_Declarations): When having
        static handlers and a non restricted profile, we use the
        type Static_Interrupt_Protection always, so we removed an
        extra wrong condition looking at the No_Dynamic_Attachment
        restriction. Simplify the code using the result of
        Corresponding_Runtime_Package.
        (Make_Initialize_Protection): Simplify the code using
        the result of Corresponding_Runtime_Package.
        (Install_Private_Data_Declaration): The No_Dynamic_Attachment
        restriction has nothing to do with static handlers. Remove the extra
        erroneous condition that was creating the wrong data type.

        is Ada or Ada-related.

        so that expression in aspect is properly analyzed. In this case
        there is no later point at which the aspect specification would
        be examined.

        * exp_ch6.adb (Expand_N_Simple_Return_Statement): When the return
        type is a discriminated private type that does not require use
        of the secondary stack, a constrained subtype of the underlying

        If the return type is originally a private type, the return
        expression is wrapped in an unchecked_conversion. If the return
        expression is used subsequently in a call to the postcondition
        function, this conversion must be undone to prevent a spurious
        error on the analysis of that call.
