Wrong.  guile *can* be built with libtool-2.2.7a out of the box,
*once* somebody has updated guile to correctly use the new libtool.

Look, I gave you several proofs already.  Why don't you start checking
the facts rather than replying with more doubts on your side?
You should also be able to see that
  cd .../libguile
  ../libtool --version

shows the wrong version.

This has nothing to do with the bootstrap procedure, which happens
*before* configure is run.

I haven't said anything about your tool, no?

The fact that guile doesn't cleanly bootstrap with
  autoreconf -vif

is something you can discuss with the guile people.  They may accept is
as a bug, or not, it's up to how they usually bootstrap their sources.
(There are no portability requirements for bootstrapping.)

Whether there is a bug in your tool or not is completely outside of my
scope.  I've showed the bug not to be in Libtool.
