Glibc exposes basename() through with _GNU_SOURCE, while musl declares it in . With musl, this results in an implicit-function-declaration error and subsequent type-mismatch errors at the callers. Include so the declaration is available on both glibc and musl. This is safe at both call sites: the arguments are local writable char[PATH_MAX] buffers filled by readlink_safe().
