I think there is some confusion on what we are discussing about.
I am referring to other applications depending upon Autoconf such as
Automake, for which it is perfectly reasonable to require a version of
Autoconf which is released. In this case AC_PREREQ is just what we
want, and we don't want to play with tests on the version numbers.
You require a version, and if nonetheless you need some specific
macro of the bleeding edge Autoconf, then ifdef is good.
That's why I'm referring to the pair AC_PREREQ/ifdef.
As far as individual tools are concerned, they just have to provide
backward compatibility, that's for sure.
