Hmm, can you point to a URL of the web archive of that thread, to see if

According to http://gcc.gnu.org/ml/gcc-patches/2011-02/msg01474.html,
this might be a bug in m4 rather than in autoconf.
Unfortunately, I don't see anything obvious in m4's NEWS that would
explain such a difference between 1.4.13 and 1.4.15.
If the problem is reliably caused by the version of m4, then can you do
a git bisect on m4 sources to pinpoint a particular m4 revision where
the problem first appears?
Unless I did it wrong (entirely possible) -
