On FreeBSD 14, this configure test produces

  checking spelling of daylight variable... 0

All existing unit tests succeed. But would it not produce more correct
results in general to set this to 1 instead of 0? That is, if we are
in the mktime()/localtime() pair, if we know nothing about the time zone,
assume that is has DST?
