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

 Description    A function identifier specified in a #pragma function
                directive is not a valid intrinsic function on this
                platform.  The function is thus never treated as an
                intrinsic, and so #pragma function can never be
                applicable to it.  Perhaps the name was misspelled,
                or perhaps the function was thought to be intrinsic,
                possibly because it is intrinsic on some other
                platform.  In the latter case, the desired result,
                that the function not be treated as intrinsic, would
                happen with or without the pragma.

 User Action    Either correct the identifier spelling or remove the
                use of the pragma.
