We have the git HEAD of autoconf packaged already, so you can easily install it with $ ACCEPT_KEYWORDS="**" emerge sys-devel/autoconf 2. The entire distribution is source-based, and whenever we need to patch the build system of a package that uses autotools, we run reautoconf and regenerate the configure script as part of the normal package installation process. The success or failure of the subsequent build isn't a perfect indicator of autoconf's correctness, but any (as of yet unreported) build failures would be interesting. You can find which packages those are with a `git grep eautoreconf` on https://gitweb.gentoo.org/repo/gentoo.git/ Since we depend so heavily on autoconf, I'm sure there are lots of developers and users who would be willing to volunteer as crash test dummies as well. We do this every time there's a new major version of GCC. Perhaps if you cut a release candidate after fixing the test failures, I could popularize it on the mailing lists and ask people to CC you on any suspicious build-failure bug reports.
