I tried with various autoconf versions, including 2.65, and also with three different versions of m4.exe ( all from http://sourceforge.net/projects/mingw/files/MSYS/Extension/m4/ ) with both dos and unix line-endings and each time ran into the same problem.
Eli, would it be possible to describe your environment? I tar.xz'ed (hopefully all of) the pertinent files via the following: git clean -dxf; autoconf -v -i -d > autoconf.log 2>&1; tar -cJf gnumake-autoconf.tar.xz autom4te.cache configure.ac acinclude.m4 configure autoconf.log I'm not sure if attachments work, or are frowned up, so here's my archive on Dropbox: https://www.dropbox.com/s/uo16sugl70rk60n/gnumake-autoconf.tar.xz Cheers, Ray.
