[Mpi-22] [MPI Forum] #59: Clarification on MPI::FILE_NULL, MPI::WIN_NULL and MPI::COMM_NULL

[Jeff Squyres]

This is worth raising to the list.

What is the rule for 2.2 -- that existing MPI applications must be  
able to run with no changes against an MPI-2.2 library?  Or is it that  
existing MPI applications must be able to compile and run with no  
source code changes against an MPI-2.2 implementation?

I hope it's the latter; this change is relatively important.
