[Mpi-forum] MPI_Type_create_struct vs. other datatype creation routines

Is there a reason why MPI_Type_create_struct was given the special 
privilege of using MPI_Aint to store displacements, while the remaining 
datatype creation routines use int? This would essentially disallow 
creation of a datatype as an offset to MPI_BOTTOM.
