    From Andreas Beckmann@21:1/5 to All on Sat Mar 16 02:30:01 2024
    Source: pvpgn
    Version: 1.8.5-3
    Severity: serious
    Tags: ftbfs sid trixie
    Justification: fails to build from source (but built successfully in the past)

    Hi,

    pvpgn FTBFS with -Werror=implicit-function-declaration which was
    recently enabled by default in dpkg 1.22.6 to support the 64-bit time_t transition. For more information, see https://wiki.debian.org/qa.debian.org/FTBFS#A2024-03-13_-Werror.3Dimplicit-function-declaration
