+
+	* ruby.c (proc_options): global load path setting moved from
+	  ruby_prog_init().
+
+	* ruby.c (incpush): renamed.  push path entry at the END of the
+	  load path array.  This makes -I directories sorted in order in
+	  the arguments.

 	* dir.c (dir_each): should check whether dir is closed during the
