Ah, indeed: getdp still uses the old format... :-(
I'm not sure if we should merge your patch for ListUtils.h as is: I
don't understand why the access functions would work (since the index
should definitely also be a long int), the I/O will be inconsistent, etc.
Would you be willing to go over the full code in ListUtils.cpp and make
it 64 bit aware?
