MPI_SIZEOF) that exist only in F90, and on the F90 extended support)

 Extended Fortran Support:

 This routine is part of the extended Fortran support, described in
 Sections 10.2.4 and 10.2.5 in the MPI-2 Standard.  Full support for these
 features `cannot` be efficiently implemented within the Fortran 90
 language and would require a nonportable iteration with specific
 Fortran 90 compilers.  MPICH has chosen to offer many of the features
 of the extended Fortran support, but there are limitations.
 For example, some routines may accept only scalars or one-dimensional
 arrays.

/*D
   MPI_SIZEOF - Return the size of a data item

   Synopsis:
   subroutine mpi_sizeof( var, size, ierr )
   <type> var
   integer size, ierr

   Notes:
   This routine returns the size of a basic element, in bytes, of the
   item passed in the first argument.  This routine is deprecated.
   Users should consider switching to Fortran 2008 storage_size() or
   c_sizeof() instead.

   Implementation limitations:
   MPICH only supports scalars and one-dimensional arrays for the
   first parameter.  Supporting higher-dimensional arrays greatly increases
   the size of the library and the executable without adding any new
   functionality.  If you have a multi-dimensional array, simply pass any
   element to 'MPI_SIZEOF'.
