| Bad, this renders this kind of warnings to be of little use.

Do you mean it?  I fail to see why.  Yes, there is a bit too much
displayed, but relevant information _is_ displayed.  I much prefer
this than mute tools.

It might be, indeed, I don't know.  But 2.13 is history.

| Well, I was surprised to see autoconf complain about something that had
| been working for ages (The real-world code that triggers this is several
| years old).

Ever tried -Wall?

| Well, does it matter? 

Yes, of course it does!  Because it makes the code more fragile, so of
course we want to get rid of transitional code.  See also the thread
about --build and the like.

| People do expect libtool and autoconf to interact smoothly, straight out
| of the box, without further intervention, like they claimed to have done
| in the past.
| => autoconf-2.54+ and libtool are incompatible.
| => libtool-1.4.3 (This also exposes the problem) is not autoconf-2.54b
| compatible.

Which is why I backed up: I thought the issue had been addressed :(
