Fortran and Fortran77

[William Gropp]

This problem has come up with MPICH as well.  Fortran 77-only  
compilers are becoming rarer; on my Mac, I only have gfortran, and  
gfortran does not accept integer*8 .  Trying to build pnetcdf on my  
Mac gave this:

One possibility would be to see if the Fortran compiler accepted

integer (kind=MPI_OFFSET_KIND)

instead of integer*8 .
