Hello all,
I guess this would be one of the few times where a change in HDF5
breaks binary compatibility between different minor HDF5 versions.
I believe there is some code that casts a hid_t (or some other hdf5
type) to a CCTK_INT (that I wrote) though I also think that that code
contains an assert that the actual value is small enough to fit into a
CCTK_INT.
