would spin in an infinate loop when passed a tm struct with all fields
set to INT_MIN. It isn't a complete fix, the loop now terminates but
mktime() does not return (time_t) -1.
I sent mail to bostic about this, who replied that the changes in 4.4BSD
were to fix this exact problem. My next step is to send mail to Arthur
David Olson, the original author and maintainer of this code.
