   Once again attempting to compile the latest
   snapshot on delysid.gnu.org, it failed as follows:

Hmm.  The GDB configure script fails to recognize the somewhat broken
curses instalation on delysid.  The problem is that delysid has both
ncurses and the old BSD curses installed, where /usr/include/curses.h
is the BSD header, and /usr/include/ncurses/curses.h is the ncurses
header.  In addition there is /usr/include/ncurses/term.h, but somehow
the same file is also installed as /usr/include/term.h.  So the
compiler is using the ncurses <term.h> together with the BSD
<curses.h>, which obviously doesn't work.  The solution is to make GDB
use the headers in /usr/include/ncurses.  Running configure with
CPPFLAGS=-I/usr/include/ncurses should work:

   $ CPPFLAGS=-I/usr/include/ncurses ./configure ...

Note that GDB is prefers -lncurses over -lcurses, so using the BSD
header wouldn't work anyway.

There isn't much we can do in GDB to detect this lossage.  I suppose
there aren't that many machines out there with that have both BSD
curses and ncurses installed in /usr.
