Stop talking about things you don't know about.
I've used SBCL on Win32 for a year and a half now. The Windows port works just fine:
http://sbcl.sourceforge.net/platform-table.html
The Windows port is not as perfect as the Linux port, in that the threading is not supported and unix signals are a bit broken, but if you can't wait for official threading/signal support on Windows, there are some experimental forks which provide that.
Even if you didn't want to use SBCL for some strange reason, CLisp is still hardly the best choice you could pick. On Windows, the most complete free choice is ClozureCL which has both threading at 64bit support (as well as native compilation, of course).
Also, Lispbox is severly outdated (old CLisp, ancient SLIME, etc). Just grab everything from SVN and enjoy latest SBCL or CCL, SLIME, Emacs/Paredit/... It's not even hard to build it yourself.
