You had the answer and let it go:  Because the time _is_ available under DJGPP
with the ANSI C time function.  That condition is intended for platforms where
such a facility is not available.  In that case, on those platforms, you'd
just defined time_t as a signed integral type and their implemented time
function would automatically return (time_t) -1.
