The iconv(3) man page has the following link to explain the iconv const inconsistency issue:

https://www5.opengroup.org/sophocles2/show_mail.tpl?&source=L&listname=austin-group-l&id=7404

The link presumably worked on 2013-01-04 when it was added to the man page, or perhaps on 2004-11-11 when it was cited by https://mail-index.netbsd.org/tech-userlevel/2004/11/12/0000.html, but unfortunately the link is dead now, and it was never archived by the Internet Archive.
>How-To-Repeat:
man iconv
>Fix:
Yes, please!

The austin-group-l archive appears to be archived at mail-archive.com now: https://www.mail-archive.com/austin-group-l%opengroup.org@localhost/  So perhaps someone can do some spelunking through the history to find what message this might have been.
