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):

cc -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection `pkg-config --cflags dbus-1` -

DVERSION=\"1.4\" -o bluemon-query bluemon-query.c -Wl,-z,relro -Wl,-z,now -L/usr/lib -lbluetooth `pkg-config --libs dbus-1`
