First, these are warnings, not errors. Not sure what's the difference, it also has -Werror passed and gcc is also 13.2.0-18, but I don't see the "all warnings being treated as errors" text.

Bug#1066543: ucx: FTBFS: cc1plus: error: ‘-Werror=’ argument ‘-Werror=implicit-function-declaration’ is not valid for C++ [-Werror]
Source: ucx Version: 1.16.0+ds-4 Severity: serious Justification: FTBFS Tags: trixie sid ftbfs User: lu...@debian.org Usertags: ftbfs-20240313 ftbfs-trixie ftbfs-impfuncdef 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.
