    2015-01-17  Eli Zaretskii  <eliz@gnu.org>
    
            * configure.ac [*mingw32*]: Only add windows-termcap.o to
            CONFIG_OBS if not building with a curses library.
            * configure: Regenerate.
    
            * windows-termcap.c: Include defs.h.  Make the whole body empty if
            either one of HAVE_CURSES_H or HAVE_NCURSES_H or
            HAVE_NCURSES_NCURSES_H is defined.
