No, I don't. (Sadly it is unavailable from the Fedora repositories
and I have never had a reason to build it myself.)

[I have a local IMAP server and I retrieve my mail into it
variously with fetchmail and getmail, so I never use pop in
Emacs.]

I see.

I don't think that makes sense, does it? There's nothing terribly
odd about my system and if the warning message from config is
true, then _by default_ I'm going to get built an insecure Emacs.

I think that --without-pop should be the default. Unconditionally.
