Struct members (OpenMPI)

[ivan-pi]

Trying to build vapaa using OpenMPI 4.1.5 and GCC v12, I hit the following errors:

Is this an OpenMPI issue?

It's probably my bug. I'll work on it tomorrow or Friday. Please just use MPICH 4.2+ for now. I haven't worked too much on implementation portability because the features were hard enough to get right with one implementation.
