+       * configure: patch from eggert.  Avoids a protection problem if
+         the original Makefile.in is read only.
+
        * configure: use move-if-change from gcc to create config.status.
          Some makefiles depend on config.status to tell if a directory
          has been reconfigured for a different host.  This change
