I wonder, should configure be checking that wborder can be found with 
something like:

AC_SEARCH_LIBS(wborder, [ncurses Hcurses cur_colr curses pdcurses], [],
     [AC_MSG_WARN([no library containing wborder found])])

and then just test that both ac_cv_search_initscr and 
ac_cv_search_wborder are not "no"?
