I've been working on GNU/kFreeBSD support of sbcl for the last
couple of days. I can now successfully build with the patch attached. It
has some problems however. I needed to get in the :os-provides-dlopen
which needs a better solution (or fix for the root cause why it's not
properly detected). Also the memory fault signal stuff is a bit weired
but only working if I set the behaviour to pre 7 FreeBSD (although I
have a FreeBSD 8 kernel).
I'd be happy if you could direct me on how to improve this thing and
finally make it suitable for inclusion in sbcl proper.
