No, I haven't.  I just see code that doesn't compile. :-)

If you continue to take this tone in your messages, I will simply
cease replying to them.  It's not me-versus-you; we're just trying to
get the job done.  Please treat me with the same respect I treat you.

The GNU/Linux iconv.h contains a prototype that uses `const char **',
as does the Solaris 2.8 version.  So, the V3 headers need to work with
those headers.  I think you should either submit a change to have
fixincludes fix this, or have autoconf detect that situation and work
around it in codecvt.h.
