Dear maintainer:

During a rebuild of all packages in unstable using autoconf 2.73
(available in experimental), this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/autoconf-2.73/

This bug will be raised to serious once autoconf 2.73 is uploaded for unstable.

Thanks.
