I'm moving the discussion to autoconf@

The problem is that sometimes you really want to support the latest stable
version of Autoconf as well as the latest development version.
Automake is a perfect example.
But for this to work, the oldest supported version of Autoconf must
support this syntax. It is quite possible that Autoconf 2.50 will the
oldest supported version for some projects in a couple of years.
So it's better to be prepared.
