This fails to compile on some system (sorry, I don't remember which one),
because off_t is not defined. Since off_t is defined by either <sys/types.h>
or <unistd.h>, here's a proposed fix. (<sys/types.h> is simpler, is required
by ISO C, does not need <unistd.h>.)

        * lib/fflush.c: Include <sys/types.h>. Needed for off_t.
