FYI, I normally install Autoconf, Automake, and Libtool from original
sources. I discovered that when I installed autoconf-archive from
original sources
(https://ftp.gnu.org/gnu/autoconf-archive/autoconf-archive-2023.02.20.tar.xz)
that this put the m4 files in the correct place so they are discovered.
After this, ./autogen.sh (using Autoconf 2.71) does not produce errors,
although it does produce 3 'obsolete' warnings. I gather that a
correction was still needed in configure.ac.
It is not good to retain stale versions of commonly-available macros.
Caching macros is useful for people who checkout the git source tree and
try to do a build, or in the case where the original macro needed to be
modified.
