Well, you can use '+' (with a bit care) in any Fortran, right?. This
is the way the MPI standard does things for some enumerations (file
modes, RMA assertions).

However, if DMDA_XYZPERIODIC and friends do no go away because of
Fortran issues, then we should definitely define
DMDA_{XY|XZ|YZ}GHOSTED.
