The change to 64-bit time is essential, of course, but I don't understand
why it has to break backward compatibility. Surely you just allocate a
bunch of new system call numbers (for the 64-bit variants) while keeping
the old ones (so 32-bit time calls still work) and bump the version
number of every library. What else is going on? (I don't have a Sparc
or I'd join your experiment.)

I'm thinking of the "later" where i386 is changed to 64-bit time_t. If
that's not backward compatible, you'll get no takers.
