Hmm, doesn't appear that he's using standard fortran unformatted files
though.  Just to document here for the benefit of other c++ slobs who
haven't had the benefit of experience in the richly diverse ecosystem
of fortran 'unformatted' file formats.  I'm simply writing out the
file from a fortran program compiled with IFC, with format="binary".
This gives me plain 32 bit ints and 64 bit reals, and that's what I need.

Thanks,
Russell
