The sparc64 port is looking to switch it's time_t definition from 32-bit to 64-bit. No effort at backwards-compatibility, we'll just do a hard-and-fast switch. With a little luck, we may do that this month. We would have to do it before 5.3, or we would have to let it wait until 6.0 (at which point we *will* have to provide backwards-compatibility). We believe we can do that now, because there aren't all that many sparc64 users, and most of them would rather get this change out- of-the-way right now. Would this make sense for the PPC port, too? I am not running freebsd/ppc on anything yet, so I don't think my opinion on this counts for much. If it does seem like a good idea, the writeup in http://people.freebsd.org/~gad/time-64/UPDATING.64BTT and the script in: http://people.freebsd.org/~gad/time-64/installworld_nk should give all the details on what would need to be done. The writeup is not perfect, but it does include a complete and explicit list of the steps which every user should follow to perform the 64-bit update. But it's half-written for people who are *testing* that change (and the installworld_nk script), and half-written as if the change has already taken place. As background, I'll note that the amd64 and ia64 ports are already using a 64-bit time_t. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
