+       * uip/scansbr.c: don't use MB_CUR_MAX if we aren't compiled
+       with multibyte support.
+
        * uip/whatnowsbr.c: factor out common code for writing ls
        shell command, and make it do more sensible buffer length
        checks. Also avoid relying on the return value of sprintf(),
