time_t is 64 bits in recent NetBSD versions even on i386 platform, therefore these assertations fail on it:
in lib/mktime.c: verify (long_int_year_and_yday_are_wide_enough, INT_MAX <= LONG_MAX / 2 || TIME_T_MAX <= UINT_MAX); in lib/getdate.y: verify (LONG_MIN <= TYPE_MINIMUM (time_t) && TYPE_MAXIMUM (time_t) <= LONG_MAX); -- Hasso Tepper
