 Message        The function "<routine name>" is not a known
                intrinsic function and cannot be used with #pragma
                intrinsic.  Pragma not applied to this function.

 Description    A function identifier specified in a #pragma
                intrinsic directive is not a valid intrinsic function
                on this platform.  The pragma will not be applied to
                this identifier, leaving it to be treated as an
                ordinary function.

 User Action    Either correct the function name to specify an
                intrinsic supported for this platform, or remove it
                from the pragma.
