I am not sure exactly what the problem is, but I'll give you some
ideas: These symbols are used for TUI, a text-based interface for
GDB. As a temporary measure, you should be able to get rid of this
error by configuring GDB without TUI: --disable-tui.

I remember having experienced some problems building TUI myself
on sparc-solaris or mips-irix, because I use a local installation
of ncurses. So the configure script sort of picks up ncurses library,
but still uses the .h files in /usr/include. So I get a discrepancy
between what the compiler thinks is available in my ncurses library,
and what is actually there. And I also get undefined symbols. I don't
know if it's possible to make it work or not (I think Michael Chastain
tried on Tru64), but you could try by adding -I/path/to/ncurses/include
to your CFLAGS (make CFLAGS='-g -O2 -I/blablabla).

Maybe it's a bona fide omission in our configure script. It's hard to
tell without knowing more about your environment. But since I don't use
TUI, I never spent the time looking into this. I just build without TUI.

Good luck,
