AFAIK, `random' is POSIX.  So at least POSIX-compliant compilers will 
have it.  Borland, of course, isn't one of them.

A known problem with `rand' that using the lower bits of the value
returned by it could get you very bad results.  OTOH, `random' is
specifically documented to have all of its bits random.
