 Message        The declaration of "<name>" has <number> parameter(s)
                but its linkage "<name>" has <number>.  Standard
                linkage will be used.

 Description    The number of parameters specified in a declaration
                does not match the number of parameters specified by
                the special linkage associated with this function or
                typedef.  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.
