| Another thing, entirely different: I will be posting shortly some simple
| patches to GDB main.c that avoid including readline and company. This
| library consumes about 30% of the code space of GDB. I don't need it,
| because I have history processin as a line discipline in my tty
| driver (thanks to A. Shepherd's CLED). There are also a lot of other
| solutions to the line editing/history problem, such as using rk, atty,
| or any editor with shell buffers, and under these readline is useless as
| well.

Fine, make it optional, because I for one want the readline stuff.  It
has one piece of functionality that line disciplines can't have, and
that is auto-completion of symbol names (ie, hit fred<tab>, and it
will try to complete fred, and fred<esc>? lists all of the names that
start with fred).
