Ray,
I tried using your bf_find_root, which is indeed much, much
simpler than what I was doing, on an example I'm working on.
My use of bf_find_root is embedded in a lot of maxima
code, which I'm not posting. bf_find_root works, but SBCL
1.0.40 produced a bunch of warnings. I am attaching them in
case they're useful.
