+ * gc.c (gc_stat_internal): add compatible layer.
+ From Ruby 2.2, keys of GC.stat are changed [Feature #9924].
+ To provide compatible layer, GC.stat add a default_proc
+ (if default_proc of given Hash object is not set).
+
+ At first use of this compatible layer of interpreter process,
+ show a warning message like that:
+ program: GC.stat[:total_allocated_object]
+ warning message: "warning: GC.stat keys were changed from Ruby
+ 2.1. In this case, you refer to obsolete `total_allocated_object'
+ (new key is `total_allocated_objects').
+ Please check <https://bugs.ruby-lang.org/issues/9924>
+ for more information."
+
+ Pleaes correct my English message :)
+
+ * hash.c (rb_hash_set_default_proc): export (in internal).
+
+ * internal.h: ditto.
