I have submitted a new 2.2 proposal to add several new datatypes to the C and C++ bindings, most of them in order to keep up with the C99 standard. This proposal also adds MPI_AINT and MPI_OFFSET as predefined datatypes. Comments are welcome.

Dave -- I like the idea of [u]int[x]_t types; that would certainly be helpful to some apps. I'm a little confused on your discussion about how bool and complex may be represented differently in each language. Are you saying that MPI_BOOL may be a different thing that [the already-existing] MPI::BOOL? Also, MPI_COMPLEX and MPI_DOUBLE_COMPLEX both already exist for the corresponding Fortran types (I can't remember offhand -- MPI_LONG_DOUBLE_COMPLEX may exist already, too). How do you propose to reconcile this conflict? -- Jeff Squyres Cisco Systems
