I will go through my old patches taking into consideration the latest
version of SUNDIALS.
I had discovered the mismatched integer sizes because of some
build failures, so it should be relatively easy to reproduce in the
latest version of SUNDIALS.
It is possible that deal.II does not yet support the latest version of
SUNDIALS, in which case we will need to keep the old version around,
perhaps as dealii-sundials or some such.

I should get around to this this week or next.

Best regards,
