It appears to me that the first three warnings are a side effect of
your assumption that <time.h> declares time() and defines time_t
when in actuality it doesn't appear to do so.

The warning about exit() is because you have default-declared it as
returning type int, which is wrong.  If you have <stdlib.h> you could
use that to declare exit() properly, or you could do it "by hand".
