On top of this as I previously noted there's the fact that autoconf -Wobsolete
doesn't complain about the old macro.
However autoconf _can_ be made to complain by adding a third parameter to old
file AC_DEFUN call, this seems undocumented (I haven't looked at the source)
however and I'm not sure if it should be used but it would be nice to have to
further smooth the transition.

(last note: I have not investigated much the AU_DEFUN([old name], [new name],
[message]) approach if someone would like to try)
