        * configure.ac, nano.c (handle_sigwinch): Create check for whether LINES and
          COLS can safely be redefined.  Fixes compilation issues with cygwin, and likely
          with newer versions of ncurses, fixes Savannah bug 28984 repoted by Andy Koppe
          and Eric Oliver via mailing list.
        * winio.c (get_mouseinput) - fix stray semicolon in code, also reported in
          bug 28984.
