Ah, thanks for the clarification. I think if we cannot make it really
bullet-proof, then it's safer to reject it outright. Do you happen to know if
anyone except openmpi would be affected? If only openmpi, then we could give
them a nudge and the issue would
likely be fixed by the time gcc 4.8 rolls out to end users.
I turns out that the current Message Passing Interface (MPI) 3.0
specification itself is affected (MPI03 module), which uses default-kind
LOGICAL (and default-kind INTEGER) with BIND(C) throughout the
specification. See http://lists.mpi-forum.org/mpi-comments/2013/02/0076.php
It is still unclear how the MPI committee will handle it.
(Unsurprisingly as the issue is only known since
