     Not quite that simple.

(1) Does time.h declare time() to return long?  Make sure it does, or
declare it yourself.

(2) The call to time() is wrong.  It should be time((long *)0), unless
of course you have an ANSI-conforming compiler and time.h gives a
prototype instead of a bare declaration (how many people do you think
are so lucky?  Not many.).
