diff-match-patch fails to build with the following error:

; caught WARNING:
;   COUNT appears to be used as an ITERATE clause keyword, in this sexpression: (COUNT 1 :INTO N). This use is now deprecated and will cease to be supported in a future version. Please use the alternative keyword COUNTING instead. If you intended COUNT to be interpreted as a function call, instead of an ITERATE clause, you must find an alternative way of calling it, at present, perhaps by using FUNCALL or APPLY.
