Source: tk707

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):
