From 62261ccb47fce9c4728cfbeb84f81d23369ab910 Mon Sep 17 00:00:00 2001
From: matz <matz@b2dd03c8-39d4-4d8f-98ff-823fe69b080e>

Subject: * object.c (rb_str2cstr): warn if string contains \0 and length  
 value is ignored.

* class.c (rb_singleton_class_clone): should copy class constant
  table as well.

* class.c (rb_include_module): sometimes cache was mistakenly left
  uncleared - based on the patch by K.Kosako.

* ruby.h: all Check_SafeStr()'s are replaced by SafeStr() to
  ensure 'to_str' be always effective.
