Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build:

--------------------------------------------------------------------------------
[...]
 debian/rules build
dh build --with bash-completion
   dh_update_autotools_config
   dh_autoreconf
configure.ac:76: warning: The macro 'AC_HELP_STRING' is obsolete.
configure.ac:76: You should run autoupdate.
./lib/autoconf/general.m4:204: AC_HELP_STRING is expanded from...
./lib/autoconf/general.m4:1553: AC_ARG_WITH is expanded from...
configure.ac:76: the top level
configure.ac:117: error: possibly undefined macro: AC_MSG_ERROR
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:158: error: possibly undefined macro: AC_MSG_WARN
autoreconf: error: /usr/bin/autoconf failed with exit status: 1
dh_autoreconf: error: autoreconf -f -i returned exit code 1
make: *** [debian/rules:6: build] Error 255
dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2
--------------------------------------------------------------------------------

The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202412/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks.
