Anything outside the body of macro is never put in configure.
Using "dnl", "#", or nothing at all, is just a matter of style
(when there are no expansion of course).

And for comments, "#" is more traditional, but that's a question
of taste, I agree.  Well, not only: more tools know how to M-q
or fontify #-comments than dnl-comments.
