Which autoconf for libstdc++

100% agreed.

Current versions of these tools are

autoconf-2.59
http://ftp.gnu.org/gnu/autoconf/autoconf-2.59.tar.bz2

automake-1.8
http://ftp.gnu.org/gnu/automake/automake-1.8.tar.bz2

Note, I don't really care what versions are used. There should be one
blessed version to rule them all, though. Also, probably a periodic
syncing with whatever is considered current, with the goal of avoiding
the trap of falling years behind....

Now that I think about it, having the autotools used to generate the gcc
configure/make bits available in the gcc download area would really be
quite a step in solving developer confusion.

If the java and c++ folks agree to this then I guess the next step would
be to post a RFC on the gcc list, and then set AC_PREREQ?
