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

Attach is a new suggested patch.

2004-02-25  J. Brobecker  <brobecker@gnat.com>

        * configure.in: Make sure that the wborder function is available.
        Otherwise, search for it in the cur_colr library.
        * configure: Regenerate.

On HP/UX, configure outputs:

        checking for library containing initscr... -lHcurses
        checking for wborder... no
        checking for library containing wborder... -lcur_colr

On Linux, configure says:

        checking for library containing initscr... -lncurses
        checking for wborder... yes

In both cases, I verified that TUI was linked in.
