program main
! This is a simple test to check that both the MPI and PMPI versions of the
! timers are available, and that they return double precision values.
! If this code links, there are no problems.

! Add a test on time1 to ensure that the compiler does not remove the calls
! (The compiler should call them anyway because they aren't pure, but
! including these operations ensures that a buggy compiler doesn't
! pass this test by mistake).
