Why do we need to use __off_t in particular here?

This file is purely internal to libc, right?  So surely we can just
use the normal off_t type, instead of the internal sys/ansi.h hack
which exists to reduce namespace pollution.

I think it is better if __off_t itself appears only in sys/ansi.h and
the header files that use it to define off_t without polluting the
namespace with anything else.  (For that matter, not sure why we don't
use _BSD_OFF_T_ like _BSD_SIZE_T_.)
