I strongly agree with that, for two reasons: - the build system is a complicated mess, and we don't have people skilled enough to fix the existing issues (otherwise we would have fixed this PR) - as a maintainer, I like to be able to regenerate files before/without doing a build, to look at the changes I'd rather have a script like libgfortran/regenerate.sh, that calls m4 and updates the tree. Then maintainers know that, if they changed any m4 file, they need to regenerate. (It does not happen that often.)
