To be honest, I don't see these two changes (changing mpi-defaults to

preferable to reinstate a 32-bit compatible pmix and fix openmpi on 32
bit until the time_t transition is

OpenMPI 5 drops 32-bit support, but otherwise does not change the API/ABI.
So it is technically not a transition, but breaks 32-bit builds.
Doesn't make it better. This is not the time to do that without tests
builds and bugs filed.

It drops 32-bit support from OpenMPI.
Because of this, I don't think the solution is to port 32-bit atomics for
armel/armhf, as it will be removed in a few

No native ones, yes.
I *think* either libatomic or libatomic_ops(?) make them
available, but very
