C
C In order to check the base, we need an address-of function.
C We use MPI_Get_address, even though that isn't strictly correct
call MPI_Win_get_attr( win, MPI_WIN_BASE, valout, flag, ierr )
if (.not. flag) then
errs = errs + 1
print *, "Could not get WIN_BASE"
C
C There is no easy way to get the actual value of base to compare
C against. MPI_Address gives a value relative to MPI_BOTTOM, which
C is different from 0 in Fortran (unless you can define MPI_BOTTOM
C as something like %pointer(0)).

CC For this Fortran 77 version, we use the older MPI_Address function
