I see. Moreover, octet-replace does the same thing as replace, but more
efficiently :-)

To optimize on LW, put
    (optimize #+lispworks (hcl:fixnum-safety 0))
and you get 118 bytes.

The type sys:int32 corresponds (singned-byte 32), which IMHO less convenient
then (unsingned-byte 32). For example, MD5 widely uses modulo-2^32 addition.
In what way sys:int32 can help to implement this?
