   Very clever! I didn't know that AC_CHECK_FUNC was using $LIBS to
   link its test program...

Except that AC_SEARCH_LIBS is clever enough itself.  It first tries to
find the function in the libraries already present.

AC_SEARCH_LIBS (initscr, [ncurses ...]), [], [AC_MSG_WARN...])
AC_SEARCH_LIBS (wborder, cur_clr, [], [AC_MSG_WARN...])

Should do exactly what you want.
