Ah, that explains it then, autoconf smelled out gm4 (unknown to me) and used it, and it was m4-1.4.15.  It chose this over m4, which was 1.4.6.  The newer m4 came from macports.

So, do we document that one needs m4-1.4.13 or older?  Ick.  Add a PREREQ line to exclude the known buggy version?  I fixed mine by rebuilding autoconf with the old m4 in the path and this fixed it.

export M4=gm4-1.4.6 before running autoconf also fixes it as well.

Thanks.
