From 5c4f8cadbd362497dc3c3136566589557ce00f1b Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Sun, 24 Jul 2022 11:44:12 -0700 Subject: [PATCH] Adjust to Gnulib bootstrap revamp * autogen.sh, autopull.sh, bootstrap-funclib.sh: New files, copied from gnulib/top. * bootstrap: Copy from gnulib/top/bootstrap (as opposed to copying from gnulib/build-aux/bootstrap, as we used to). * bootstrap.conf (bootstrap_post_pull_hook) (bootstrap_post_import_hook): New functions.
