undefined (asdf:system-license on clisp+cywgin

Hi,

I am trying to load nlisp on my clisp+cygwin insallation, and it is
breaking on the undefined function asdf:system-license.

(It -- the nlisp package -- is loading flawlessly on linux+sbcl)

I looked in asdf.lisp, and I see that system-license is an exported
function, but I don't see it defined anywhere. Same with a few
others, like unix-dso for example.

I am further puzzled by the hash marks in the package definition:
(defpackage #:asdf
(:export #:defsystem #:oos #:operate #:find-system #:run-shell-
command
#:system-definition-pathname #:find-component ; miscellaneous
#:hyperdocumentation #:hyperdoc

I guess that I am missing something, but what?

thank you,

Mirko
