Hello,
  I have a naive question. MPI3 has Fortran binding in forms like this:

      MPI_Send(buf, count, datatype, dest, tag, comm, ierror) BIND(C)
         TYPE(*), DIMENSION(..), INTENT(IN) :: buf
          INTEGER, INTENT(IN) :: count, dest, tag
          ...

   So how to interpret BIND(C) here?  Is it to say this interface is interoperable with C? But I find the interface arguments are not interoperable, e.g., INTEGER, instead of C_INT.
   Thank you.
