 Message        The declaration of "<name>" has an unknown number of
                parameters and cannot be used with the linkage
                "<name>".  Standard linkage will be used.

 Description    If a special linkage specifies parameter information,
                the declaration must not specify an unknown or
                variable number of parameters.  The special linkage
                was specified via the #pragma use_linkage directive.
                Because of this mismatch, the compiler will ignore
                the special linkage and use the standard linkage
                instead.

 User Action    Make sure the number of parameters specified by the
                special linkage match the number of parameters in the
                function type.
