[Mpi-forum] Reserved MPI_ prefix & namespace in C and Fortran

[Rolf Rabenseifner]

I updated the ticket 343 with the now hopefully final text 
for the terms chapter (after Bronis', Bill's and Martin's comments)
see
https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/343
and the files attached to the ticket.

I hope that now all can agree with this correction of the 
existing inconsistency as detected in the public review
and discussed in the previous emails.

--------------------------------
Latest summary of the necessary MPI-2.2 erratum 
in Sections 2.6.2 - 2.6.4 (modifications indented):

C:
>   "Programs must not declare
       names (identifiers), e.g., for variables, functions,
       constants, types, or macros, 
>    beginning with the prefix MPI_.
>    To support the profiling interface, programs 
       must 
>    not declare functions with names beginning with the prefix PMPI_."

Fortran:
>   "Programs must not declare
       names, e.g., for variables, subroutines, functions, 
       parameters, derived types, abstract interfaces, or modules,
>    beginning with the prefix MPI_.
>    To avoid conflicting with the profiling interface, programs 
       must 
>    also avoid 
       subroutines and 
>    functions with the prefix PMPI_."

C++ (not visible in MPI-3.0 due to removal of C++):
>   "Programs must not declare
       names (identifiers), e.g., for variables, functions,
       constants, types, or macros, 
>    in the namespace MPI."

And change-log entry

    Sections 2.6.2 and 2.6.3 on pages 18 and 19, and
    MPI-2.2, Section 2.6.2 on page 17, lines 41-42, 
    Section 2.6.3 on page 18, lines 15-16, and 
    Section 2.6.4 on page 18, lines 40-41.
    This is an MPI-2 erratum: The scope for the reserved prefix MPI_ 
    and the C++ namespace MPI was extended to any name.
