        * 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
        type is created to convey the proper object size to the backend.
        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.
