--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> --- I've been working a bit on this in my autotools-tinkering branch in my userspace; it's nowhere near done yet, though... I'm also mirroring the branch on GitHub: https://github.com/cooljeanius/gcc/tree/me/autotools-tinkering I should probably also be opening some bugs against autoconf for some of the screw-ups I've noticed that autoupdate causes when running it on some of gcc's autoconfigury... (e.g. nested AC_TRY_COMPILEs leading to stray _au_m4_changequote([,])s when being upgraded to AC_COMPILE_IF_ELSE, macros in comments getting expanded, stuff inside AC_REQUIRE getting autoupdated even when that breaks the usage of AC_REQUIRE, config/multi.m4 getting broken due to something having to do with argument quoting, spacing/line-length getting ruined, etc.)
