Ah, I didn't initially put those in the list because I put in
ERRHANDLER functions (i.e., function pointer arguments) -- but you're
pointing out that we should also do the whole extraordinarily-
confusing attribute conversion stuff, right?
Should we open the possibility of treating F2003 attributes exactly
like C attributes? This would make the attribute situation far less
confusing than it is now, IMNSHO...

MPI_WTIME -- good call; let's add that to the list.

Ah, I wasn't aware of that. In OMPI, all of our handles are pointers,
so I think if we cover a few types (eg., communicator and datatype) in
the sample with OMPI and some other MPI that uses integers, we'll be
covered.
So here's a new list:
6-function MPI
- MPI_INIT
- MPI_FINALIZE
- MPI_SEND
- MPI_RECV
- MPI_COMM_RANK
- MPI_COMM_SIZE
Some non-blocking functions
- MPI_ISEND
- MPI_IRECV
- MPI_WAITALL
A function with a string
- MPI_GET_PROCESSOR_NAME
Memory pointers
- MPI_ALLOC_MEM
- MPI_FREE_MEM
Varargs
- MPI_PCONTROL
Functions dealing with function pointers
- MPI_COMM_ERRHANDLER_SET
- MPI_COMM_ERRHANDLER_GET
Returns double
- MPI_WTIME
Along with at least the following pre-defined MPI handles (others can
be included of course):
Basic handles
- MPI_INTEGER
- MPI_COMM_WORLD
"Weird" handles
- MPI_BOTTOM
- MPI_STATUSES_IGNORE
Function pointer handle
- MPI_ERRORS_ARE_FATAL
