Don't know if this is something that should be fixed.

In master,

  git clean -xdf
  ./autogen.sh

creates a number of modified files in build-aux

  git status

  On branch master
  Your branch is up to date with 'origin/master'.

  Changes not staged for commit:
    (use "git add <file>..." to update what will be committed)
    (use "git restore <file>..." to discard changes in working directory)
          modified:   build-aux/config.guess
          modified:   build-aux/config.sub
          modified:   build-aux/install-sh
          modified:   exec/config.guess
          modified:   exec/config.sub
          modified:   exec/install-sh

This is on macOS 14.2.1 (23C71), with

  brew info autoconf
  ==> autoconf: stable 2.72 (bottled)
  Automatic configure script builder
  https://www.gnu.org/software/autoconf
  /usr/local/Cellar/autoconf/2.72 (71 files, 3.6MB) *
    Poured from bottle using the formulae.brew.sh API on 2024-01-04 at 21:35:37
  
  brew info automake
  ==> automake: stable 1.16.5 (bottled)

So it looks like I got a new Autconf recently.
