[mpi-21] MPI-2 MPI_Comm_spawn inconsistency

[Rolf Rabenseifner]

This is a proposal for MPI 2.1, Ballot 4.

This is a follow up to:
  Significance of non-root arguments to MPI_COMM_SPAWN 
  in http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/index.html
with mail discussion in
  http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/discuss/spawn/

The problem may be clarified with the following proposal

Proposal for MPI 2.1, Ballot 4:
-------------------------------
Add in MPI-2.0, page 88, after line 24:

Advice to users. If the non-root processes do not use MPI_ERRCODES_IGNORE,
then they have to allocate the appropriate number of entries (see maxproc 
at root) in the array_of_errcodes although the maxproc argument is 
unused in non-root processes. (End of advice to users.)
-------------------------------

Discussion should be done through the new mailing list
mpi-21_at_cs.uiuc.edu.

I have sent out this mail with CC through the old general list
mpi-21_at_[hidden]

Best regards
Rolf
