I can't see the code from here. The first failure to recognize the
PARAMETER definition apparently gives rise to the others. According to
the message, you already used the name MPI_STATUS_SIZE in mpif-config.h
and now you are trying to give it another usage (not case sensitive) in
the same scope. If so, it seems good that the compiler catches it.
