! Note about these declarations: these are "external" functions in
! mpif-common.h.  However, if we don't declare them here, compilers will add
! them to the "mpi" module namespace, and result in linker errors if MPI
! F90 applications try to use them.  because the implementations of
! these functions are not in the MPI module namespace -- they're the F77
! functions.
