 Message        <Context> the declaration for the prototyped
                intrinsic function "<name>" is incorrect:  <problem>.

 Description    A function that could be handled internally by the
                compiler and requires a prototype, has been declared
                with a prototype that does not agree with what the
                compiler expected to see.  The function might be
                intended as a similarly-named replacement for the
                compiler-known function, or the prototype might be
                incorrect.  The source must be modified to specify
                the intended behavior.

 User Action    If the function is intended to refer to the
                compiler-known routine, the appropriate header file
                should be included in the source.  Alternatively, the
                prototype could be modified as specified in the error
                message.  If the function is intended to be a
                replacement for the compiler-known routine, disable
                the intrinsic version by specifying "#pragma
                function(function_name)" in the source file.
