I don't see any likely reason to switch to a new version other than the
latest (of autoconf and automake, I don't know about libtool).
An update needs to deal with the issues I listed in
<http://gcc.gnu.org/ml/gcc-patches/2007-02/msg00842.html>. It will also
need testing in a --with-build-sysroot configuration, in view of the
problems I observed
<http://gcc.gnu.org/ml/gcc-patches/2008-01/msg00912.html> when the
libstdc++ configure files were accidentally regenerated with newer
autoconf and automake. The new directory variables do mean this needs
careful coordination across gcc and src, but it should be easier than the
update from 2.13 to 2.59 was.
