> Due to MiG requiring the subsystem to be defined early in order to know the
> size of a port, this was causing a division by zero error during ./configure.
> We could have just move subsystem to the top of the snippet, however it is
> simpler to just remove the check given that we have no plans to use some other
> MiG anyway.

> We force RETURN_CODE_ARG to use retcode which is a no-op.
