Have a look at the last paragraph of Section 10.2.2 of the MPI-2
standard. Functions from MPI-1 that take address-sized arguments use
INTEGER in Fortran. This was obviously a problem, which is why the
functions from MPI-1 that take an address-sized argument are
depricated in favor of new functions in MPI-2 that take proper
address kind arguments.

Two options:

   1) Use MPI_TYPE_STRUCT with INTEGER arguments

Hope this helps,
