Now that m4 1.4.5 is released, should we update the web pages to recommend
it?  m4 1.4.4 has some flaws, including an exploitable buffer overflow on
platforms that lack ecvt(3), that are inherited by autom4te.

I haven't seen the mail I sent to autotools-announce or info-gnu (I'm not
sure who moderates them, or if my post was rejected or still in the
queue), but a copy of the release announcement is here:
