Correct. The whole reason for the largefile stuff was to ease the
transition from 32-bit off_t to 64-bit off_t. Even now, I don't think
Linux, Solaris, or AIX enable 64-bit off_t by default. Heck, Solaris
and AIX still default to building 32-bit /binaries/, even though
they've been on 64-bit CPUs for ages. My guess is the "transition
period" will last at long as x86 CPUs exist :) Tru64 always ran on the
64-bit Alpha, so it's another OS that never had to deal with it.
