It occurs to me that this is likely not going to be enough for you,
Like it or not, there's still installed OMPI's out there that will
show this old behavior. Do you need to know / adapt for those? If
so, I can see two ways of you figuring it out:
1. At run time, do a simple call to (Fortran) MPI_INITIALIZED and see
if you intercept it twice (both in Fortran and in C).
2. If that's not attractive, we can probably add a line into the
ompi_info output that you can grep for when using OMPI (you can look
for the OPEN_MPI macro from our <mpi.h> to know if it's Open MPI or
not). Specifically, this line can be there for the "fixed" versions,
and it simply won't be there for non-fixed versions.
