This a MPI-2 errata based on an existing inconsistency. Therefore we do not want to rewrite the three sections.

I missed that - sorry. I am juggling just too many things :-( My response was obviously in the context of MPI 3.0.

The current proposal is simple:

C:

...

"Programs must not declare names (identifiers), e.g., for variables, functions, constants, macros, types, or namespaces, beginning with the prefix MPI_."

'Namespaces' is just plain wrong. The minimum change to correct that is to change "macros, types, or namespaces" to macros, or types". You could, with benefit, add "labels, tags, members," somewhere.

Fortran:

...

"Programs must not declare names, e.g., for variables, parameters, functions, derived types, or abstract interfaces, beginning with the prefix MPI_.

'Functions' should be 'procedures' and you could, with benefit, add "modules, COMMON blocks," after it. Regards, Nick Maclaren.
