CLISP has the "interesting" characteristic of expanding this:

(setf (foo X) Y)

to this:

((setf foo) Y X)

The CPS transformer breaks violently on this. You should update the
arnesi lib (which contains the cps transformer) since i've only
recently taught it to handle these forms. [the easiest way to update
ucw (and arnesi and yaclml and iterate) is to run the bin/update.sh
script.]

ouch! have you tried this (unpack it and put the resulting files in
you cygwin path):

http://ct.radiology.uiowa.edu/~jfmeinel/tla-short-path/

if you use that to get ucw the file names are shortened client side to
avoid those too-long-filename errors (nto that i've tried).

p.s. - did you resolve that MOP issue?
