Relasing Autoconf 2.70?

[Stefano Lattarini]

Hello Autoconfers.

In Automake 1.14 (whose developement will start in about two weeks
from now, once I've released Automake 1.13), I'd like to start relying
unconditionally on the Autoconf-provided macro 'AC_CONFIG_MACRO_DIRS'.
But that macro (and its companion 'AC_CONFIG_MACRO_DIR_TRACE') is so
far only present in the development version of Autoconf.  So, could we
start thinking about cutting an Autoconf release?

The stuff still pending about the requirement of a POSIX shell:
<http://lists.gnu.org/archive/html/autoconf-patches/2012-11/msg00020.html>
can IMHO be delayed without problems to Autoconf 2.71 (especially
considering that we still only have tentative patches in that direction).

Objections, opinions?

Regards,
  Stefano
