 33	-- Note: wrapping gtk_list/tree_store_set is problematic since it's
 34	-- a variadic function but also its not-variadic variant
 35	-- (gtk_list_store_set_valist) is not easy to use from within
 36	-- ewg-wrapped libraries since currently it's not easy/possible to
 37	-- wrap va_list-using functions. Using the plain
 38	-- gtk_list_store_set_value can be an answer but I haven't checked
 39	-- its performance (2005-05-16 Paolo)
