Hello Sylvain,

Yes, the new ids for optional Fortran datatypes are wrong.

So, as with other Fortran types, IMHO they need to map to C types, aka the IDs
should map. Therefore, we should _not_ increase the number of predefined types
-- these are fixed as representable by C...

The below patch does just that and fixes Your testcase!

George, what do You think? Could You check, please?

Best regards,

PS: Yes, You're perfectly right, that the number of Fortran tests (esp. with
regard to optional ddt) are too low.
Several features of MPI (MPI-2 are not well represented in MTT).
