Sorry, no can do.

CMUCL uses signals to a great extend: to single-step _itself_, to provide
exception handling, etc. CMUCL _needs_ the registers in the signal
handler, it needs to be able to longjmp out of the handler back to the
toplevel, it needs to be able to mmap an area larger then physical memory
(I've heard of some NT weakness in that area), etc...

Win32 doesn't provide such services, nor does gnu-win32.

I'm afraid a porter to win32 would have to rewrite quite a lot :-(.
