    Version: 1.11.7-1.1

    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):
    gcc -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -O -g -DVERSION=1.11 -Wdate-time -D_FORTIFY_SOURCE=2 -c -o env.o
    env.c
