Hello,

Re: http://sources.redhat.com/ml/gdb-patches/2004-02/msg00654.html

On HP/UX, the GDB build fails during the link due to a missing wborder.
I found the symbol in libcur_colr.sl. To fix the build, I suggest the
following change, although I could conceive that this is not the best
way of handling this. Comments and suggestions warmly welcome.

2004-02-23  J. Brobecker  <brobecker@gnat.com>

        * configure.in (LIBS): Add -lcur_colr when TUI is enabled and
        when using the HP curses library.
        * configure: Regenerate.

Tested on HP/UX 11.00, and x86-linux.
