I notice later in dwarf2out_finish() of dwarf2out.c that we have...


 if (!IS_ABSOLUTE_PATH (filename))
    add_comp_dir_attribute (comp_unit_die ());
  else if (get_AT (comp_unit_die (), DW_AT_comp_dir) == NULL)
    {
      bool p = false;
      htab_traverse (file_table, file_table_relative_p, &p);
      if (p)
        add_comp_dir_attribute (comp_unit_die ());
    }

perhaps gen_compile_unit_die()  needs a similar else statement?
