Please try to avoid @zino.

Ralf, "possibly more than once" is not exactly hinting at 855 times, which
is what happened to me then.  But anyway, I realize it's not happening any
more, so there is nothing to fix and I'm happy to do the upgrade...

Well, here's the old one from CLN's ChangeLog:

2004-08-25  Bruno Haible  <bruno at clisp.org>

        * autoconf/ltmain.sh: Upgrade to libtool-1.5.6.
        * m4/libtool.m4: New file, from libtool-1.5.6 with modifications:
        2004-08-22  Bruno Haible  <bruno at clisp.org>
                * m4/libtool.m4: Add support for Comeau C++ on Linux.
                Reported by Prof. Roberto Bagnara <bagnara at cs.unipr.it>.
        * autoconf/aclocal.m4: Regenerate.

Maybe you want to contact Roberto Bagnara?
