* string.c (rb_str_delete_bang): delete! should take at least 1

  argument.

* eval.c (ev_const_defined): check Object's constant if no current
  class is available (e.g. defining singleton class for Fixnums).

* eval.c (rb_yield_0): should check based on rb_block_given_p()
  and rb_f_block_given_p().
