Gentoo 32 bit uses timespec(64).  But not all distros do, and POSIX does
not mandate it.  POSIX just says time_t is a signed integer.

FreeBSD 8 defines time_t as int32_t.

QNX 6 also hass 32 bit time_t.

I'm happy to EOL any OS that still uses 32 bit time_t.  If we do so we
just need to be explicit about it.  Then we have no remaining 32 bit
only problems.
