Now that MPI 2.1 is close to completion, it is time to look at issues for
MPI 2.2. Please send any items you may have for 2.2 to
mpi-22 at lists.mpi-forum.org and/or upload them to the wiki (and let us know).
I had made a note of the following items from the last meeting that were
deferred to 2.2:

* support for long long in maxloc, minloc

* fix meaning of first two sentences in intercommunicator barrier

* Ex 5.8 uses old style MPI_UB

* Many functions say "integer" instead of "nonnegative integer"

* const in C++ bindings 

* IN, OUT, and INOUT handle types broken 

* MPI_CHAR, MPI::CHAR should be signed char or char?

* Need 64-bit sizes for count in messages

* Sizes of MPI_Aint and MPI_Offset should not be different

* New predefined types MPI_AINT and MPI_OFFSET

* New predefined types corresponding to new types in C99, Fortran 2003, and
C++ some year
