Yes. The MI code is already done and there's not much MD code that
is expected to break. It's mostly the structures that change. This
is especially painful on sparc64 because it's big-endian. I assume
that sparc64 passes syscall arguments in registers, so the syscalls
that take a time_t do not change except that there's no sign extension
prior to use. You can preserve the ABI until 2038 by ignoring the
upper 32-bits in that case.
