Not if it can be helped. CVS autoconf requires a whole lot of changes
in `configure.in's to keep it quiet, and automake is still usable
without any of these features. I'm totally against coupling releases
of software unless it can't be helped. Which means that I'd really
like if automake CVS could still be used without autoconf CVS, even
after it is improved to make use of --trace and such. Yes, this means
keeping backward-compatibility code. Which, IMO, is a good thing.
I have enough trouble convincing other developers of other projects,
such as Kaffe, to use libtool and automake from CVS, because they
offer features we really need. I'd rather not force them to install
and use autoconf CVS too.

This problem has just cost me a whole hour of investigation, trying to
figure out what the heck was wrong with AC_PROG_LN_S, which was where
bash reported the error to be (after the matching backtick). I even
suspected someone had hacked into the lab and replaced bash with some
non-working shell!
So I installed the following patch in automake, so that we don't have
to change autoconf.

* m4/missing.m4: Print the backtick in a way that won't cause
autoconf CVS to emit any warnings.
