win_dup_fn test causes gfortran failures

[jsquyres]

@ggouaillardet The new win_dup_fn fortran tests cause failures on old compilers. For example: http://mtt.open-mpi.org/index.php?do_redir=2265. I'm not sure what the exact issue is; perhaps that older gfortran doesn't like POINTER...?

Can you please update the test to avoid this issue?

[ggouaillardet]

ok, will do

Fixed!
