commit c1c797c18909ade012ab3e41df5533cbc7d9e148 Author: Marco Casaroli <[email protected]> AuthorDate: Thu Oct 8 22:00:34 2026 +0200 include/unistd.h: Declare issetugid(). libc builds issetugid() (and sched/group provides it with CONFIG_SCHED_USER_IDENTITY), but no header declared it, so a program that calls it gets an implicit declaration.
