Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

This is most likely caused by a change in dpkg 1.22.6, that enabled -Werror=implicit-function-declaration. For more information, see https://wiki.debian.org/qa.debian.org/FTBFS#A2024-03-13_-Werror.3Dimplicit-function-declaration

Relevant part (hopefully):
