[MPIWG Fortran] Question about 388 errata

[Bill Long]

I think the intent is "To take advantage of the features enabled by TS 
29113, new routines are needed...".  The main thrust of the TS, as far 
as MPI is concerned, is the capability to pass an argument by (pointer 
to a ) descriptor, rather than as a plain address.  This is only done 
for choice buffer arguments.

The actual side effect of this is that for routines that do not have 
choice buffer arguments (MPI_Barrier.... )  the implementation layer in 
the C library is the same as before.  Only for the ones with choice 
buffer arguments is there a need for both the legacy version (with a 
(void *) format parameter) and the new one that handles pointer to a 
descriptor.

Cheers,
Bill
