This patch is already in Gnulib since 2020-12-09. But when people run 'autoreconf' on an existing released tarball, they are effectively combining an older Gnulib with a newest Autoconf. Why do people do that? The point of tarballs is that you can run './configure' right away. If people want to modify the build infrastructure, it would often be more reasonable to start off the git repository of the package (possibly from a specific release tag or release branch). Bruno
