+
+Sun Oct  8 13:20:26 2000  Guy Decoux  <decoux@moulon.inra.fr>
+
+	* eval.c (POP_SCOPE): not just set SCOPE_DONT_RECYCLE, but do

+Fri Oct  6 12:50:52 2000  Yukihiro Matsumoto  <matz@ruby-lang.org>
+
+	* array.c (rb_ary_plus): use to_ary(), not Check_Type().
+
+	* array.c (rb_ary_concat): ditto.
+
+	* gc.c (rb_gc): use __builtin_frame_address() for gcc.
+
