Does this mean, that the C++ datatypes BOOL, COMPLEX,
DOUBLE_COMPLEX and LONG_DOUBLE_COMPLEX
have to be available in C and Fortran ?  If yes, what  are
the names of them in C and Fortran ?
Or is the statement in Annex  1.1  (MPI 2.1, page 495, line 1)
"C++-Only Named Predefined Datatypes"
indicating, that they are not available in C and Fortran versions
of MPI 2.1 ? In this case, the sentence above should
be corrected.
