Mon Jan 15 16:00:07 2001 Yukihiro Matsumoto <matz@ruby-lang.org>

* pack.c (pack_unpack): should check associated pointer packed by
	  pack("P").  restriction added.

Sun Jan 14 21:49:28 2001  Koji Arai  <JCA02266@nifty.ne.jp>

	* sprintf.c (rb_f_sprintf): simple typo.  binary base should be 2,
	  not '2'.

	* re.c (rb_reg_s_last_match): should explicitly return nth match.
