I may pick it up eventually; but I have a list of other things first,
so certainly won't mind being beaten to.

What's more is, you don't need that.  Autoconf has all the obsoletion
machinery in place already.

Not now, if we can avoid it.  I don't want to tighten the dependency
chain around the user's neck more than necessary.  In case you didn't
see this fleeting by: there are distributors out there patching Libtool
1.5.x to run with Autoconf 2.13...
