* re.c (rb_reg_expr_str): should treat backslash specially in

  escaping.

* io.c: complete off_t handling; missing argument for
  fptr_finalize(); polished rb_scan_args call.

* dir.c: wrap multi-statment macro by do { } while (0)

* eval.c, numeric,c, sprintf.c, util.c: ditto.

* bignum.c (rb_big_eq): check `y == x' if y is neither Fixnum,
  Bignum, nor Float.
