Hi, Out of curiosity, I started this transition on some packages from experimental and I observed that deborphan is not without «disruption». Indeed, the added suffix t64 to their name means that the updated libraries are listed by deborphan even if they are required by other packages. I suspect that deborphan did not take into account the Provides: field. Is this something to be reported to deborphan as it could also be in some other cases than this time_t transition? or wait and see... ;-)
