Hi MPICH, I noticed that some of the tests in test/mpi/f08 still work with 'use mpi' instead of  'use mpi_f08', mostly in the pt2pt folder. These seem to be copies of the tests in f90 which in turn have been generated by f77tof90. Shouldn't these tests be converted to 'use mpi_f08'? If so, would you be interested in a PR that fixes this? I would need to do this anyway. Kind regards, Gregor Corbin PS.: The interfaces for 'use mpi' and 'use mpi_f08' are probably too different for an automatic conversion to be practical (how to change all the integers to type(mpi_xxx) for example?).
