C This tests the null copy function (returns flag false; thus the
C attribute should not be propagated to a dup'ed communicator
C This is must like the test in commattr2f

C The only difference between the MPI-2 and MPI-1 attribute caching
C routines in Fortran is that the take an address-sized integer
C instead of a simple integer. These still are not pointers,
C so the values are still just integers.
