Description Agostino Sarubbo gentoo-dev 2022-11-19 08:40:20 UTC 
https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/

Issue: app-admin/sysklogd-2.4.4 fails to compile (CLANG-STRICTER-SYSTEM).
Discovered on: amd64 (internal ref: clang-stricter_tinderbox)

NOTE:
(CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode

This machine uses clang with CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types -Werror=deprecated-non-prototype

This has -std=c99 so I wouldn't expect it to warn without the -Werror (i.e. you're opting in to it, rather than letting it happen "naturally" where implied default is C17 or whatever and it really will break when default changes.)
