3.2.6 Clarification of Binding of MPI_TYPE_SIZE

This clarification is needed in the MPI-/ description of MPI_TYPE_SIZE, since the issue repeatedly arises. It is a clarification of the binding.

Advice to users. The MPI-/ Standard specifies that the output argument of MPI_TYPE_SIZE in C is of type int. The MPI-/ Forum considered proposals to change this and decided to reiterate the original decision. (End of advice to users.)
