This function will probably be removed in FreeBSD 16. But the old symbol will remain, for backwards-compatibility. Set the symbol version now, so that the current version of libc will still be able to compile on future versions of FreeBSD.
If and when the
readdir_rfunction does get removed, libc's CI will start to fail. But the crate itself will continue to build, thanks to this PR.Sources
