I have some problem with the build process in current git master:

Hunting down a `m4` file defining `AC_DEFINE_DIR` on the internet fixes
it:
```
$ git clean -xdf
$ git reset --hard
$ mkdir m4
$ curl -o m4/ac_define_dir.m4

Was it maybe forgotten to add the `ac_define_dir.m4` file to the
repository? Or is something amiss on my system? I run Debian Testing
(Trixie).
