FreeBSD has 64bit time_t everywhere except i386. We looked at compat shims
and found like 200 system calls would need compat shims to keep a stable
ABI. Creating a new ABI is mostly a matter of fixing the places that know
time_t is 32 bit on i386.

Most likely, though, it will just be retired 15 years or so before the
deadline.

Time_t was still 32 bits last I checked on i386 and a few others...

I'll only be 72... with LORAN-C retired in the US the last of the
potentially problematic[*] code I've deployed is gone.
