if jenkins does not do that i'm going to kick ken in the shins.
That's right, both of them.

I think you're looking for the opposite question.
MPI_AINT_CAST_TO_VOID_PTR is used throughout the MPICH code base.
ROMIO should use MPI_AINT_CAST_TO_VOID_PTR, providing it's own (stubed
out?) version if that macro is not available.

but whatever we do, I cannot break the build. deep shame upon me for
thinking this "obviously correct" two liner did not require a bit more
