Hi,
thanks.
but, in case of mpicc, it can be ignored, but in case of mpif90, it is still
an issue.
e.g. hello_mpi.f90 program
####################
program main
   use mpi
!
! implicit none
!
  integer error
  integer id
  integer p
  real ( kind = 8 ) wtime
!
!  Initialize MPI.
!
  call MPI_Init ( error )
!
!  Get the number of processes.
!
  call MPI_Comm_size ( MPI_COMM_WORLD, p, error )

!
!  Get the individual process ID.
!
  call MPI_Comm_rank ( MPI_COMM_WORLD, id, error )
!
!  Print a message.
!
  if ( id == 0 ) then

    wtime = MPI_Wtime ( )

    write ( *, '(a)' ) ' '
    write ( *, '(a)' ) 'HELLO_MPI - Master process:'
    write ( *, '(a)' ) '  FORTRAN90/MPI version'
    write ( *, '(a)' ) ' '
    write ( *, '(a)' ) '  An MPI test program.'
    write ( *, '(a)' ) ' '
    write ( *, '(a,i8)' ) '  The number of processes is ', p
    write ( *, '(a)' ) ' '

  end if

  write ( *, '(a)' ) ' '
  write ( *, '(a,i8,a)' ) '  Process ', id, ' says "Hello, world!"'

  if ( id == 0 ) then

    write ( *, '(a)' ) ' '
    write ( *, '(a)' ) 'HELLO_MPI - Master process:'
    write ( *, '(a)' ) '  Normal end of execution: "Goodbye, world!".'

    wtime = MPI_Wtime ( ) - wtime
    write ( *, '(a)' ) ' '
    write ( *, '(a,g14.6,a)' ) '  Elapsed wall clock time = ', wtime, '
seconds.'

   end if
 !
 !  Shut down MPI.
 !
  call MPI_Finalize ( error )

  stop
  end
