Personally, I've been running with bleeding-edge libtool installed at the
same --prefix as autoconf 2.60b, when bootstrapping M4.  When distributing
m4 1.9b (someday it will be stable enough to post a release candidate to
alpha.gnu.org), the distro will be self-contained; so this issue only
affects people bootstrapping from CVS.  I'm not sure whether this is a
libtool limitation, or how best to address it in the m4 bootstrap script.
 Maybe someone else can suggest some ideas?
