Hi, I checked add-to-list fucntion in subr.el and I saw some fixme
comments. Is this actually a warning? If so, should this warning
return non zero status code when users specified `(setq
byte-compile-error-on-warn t)`?

I tried following command to compile:

----
$ emacs -Q -batch --eval '(setq byte-compile-error-on-warn t)' -f batch-byte-compile ./foo.el

In foo:
foo.el:9:13:Error: `add-to-list' can't use lexical var `a'; use `push' or
    `cl-pushnew'
$ echo $?
0
----

But, it returns 0. Is this desired behavior? or a bug?
