* bignum.c (rb_big_cmp): use dbl2big() for Floats, instead of

big2dbl().

* bignum.c (Init_Bignum): rb_big_zero_p() removed.  There may be
  Bignum zero.

* eval.c (rb_call0): new argument added for original method name.
  preserve original method name in frame->orig_func.

* eval.c (is_defined): use frame->orig_func, not last_func.

* eval.c (rb_eval): ditto.

* eval.c (method_call): supply data->oid also to rb_call0().

* object.c (rb_class_allocate_instance): call rb_obj_alloc() when
  called from alias, thus invoke original "allocate".

* eval.c (remove_method): removing allocate from classes should
  cause NameError.

* hash.c (rb_hash_equal): should check default values.

* ext/socket/socket.c (s_recvfrom): update RSTRING len.
