    [warningectomy] unused variable (shadowed)
    
    dia_xml.c:273:17: warning: unused variable 'ret' [-Wunused-variable]
          xmlDocPtr ret = xmlDoParseFile(fname, &error_xml);
                    ^
    dia_xml.c:300:15: warning: unused variable 'err' [-Wunused-variable]
      xmlErrorPtr err;
                  ^
    The first one was actually a bu which would have failed with files
    missing encoding and not utf-8.
