I am not sure because I have no complete overview over the URL library.
But in many places dynamic binding is used where one indeed must modify
the globally visible value of variables. See for example the definition
of the function "url-http-activate-callback". By the way: The code uses
"(declare (special ...))" to mark these cases and to pacify the
byte-compiler. Someone with CVS write access could replace these with an
equivalent non-CL statement, i.e., append the named variables to
"byte-compile-bound-variables".

Isn't that a matter of taste? I find it more intuitive to use "append"
and "list" for list operations and "cons" for simple cells. But I am no
lisp expert.
