The patch is OK.

Checked in as Rev. 130914 with one modification.

Checked in was:

   gfor_fndecl_in_unpack = gfc_build_library_function_decl (
         get_identifier (PREFIX("internal_unpack")),
-        pvoid_type_node, 1, pvoid_type_node);
+        void_type_node, 2, pvoid_type_node, pvoid_type_node);


The original patch kept the pvoid_type_node for the return value.

Thanks for the patch.

Tobias
