(convert-from-uffi-type ... :struct) under mcl

i have what, i think, is a bug:

FFIGEN> (uffi::convert-from-uffi-type '(:* (:* :double)) :struct)
(:* (:* :DOUBLE-FLOAT))
FFIGEN> (uffi::convert-from-uffi-type '(* (* :double)) :struct)
(:* (:ADDRESS :DOUBLE-FLOAT))
FFIGEN> 

the second form isn't a valid openmcl ffi typespec and the first form
errors on sbcl.  is this a bug (then i'll go ahead and fix it) or am i
just missing something?

just out of curiosity, since there will never be no c type named "*",
why is CL:* used and not :*?
