+	* utils.cc (octave_vsnprintf): Return value of vsnprintf is int,
+	not size_t.  Make sure there is some space left in the buffer for
+	vsnprintf versions which return the number of characters written
+	even when the buffer is too short.

 	* debug.cc (get_user_function): Use dynamic_cast, not static_cast.
