I implemented a FillMem() function that calls FillChar(). The parameter 
are differently defined. Then changed my code as follows:

  var
    msgp: TfpgMessageParams;
  begin
-  fillchar(msgp, sizeof(msgp), 0);
+  FillMem(@msgp, sizeof(msgp), 0);
    msgp.user.Param1 := 2;
    msgp.user.Param2 := x+10;


Finally that warning disappeared.

The FillMem() implementation is as follows:

procedure FillMem(Dest: pointer; Size: longint; Data: Byte);
begin
   FillChar( Dest^, Size, Data );
end;
