+       Rewrite fts.c not to change the current working directory,
+       by using openat, fstatat, fdopendir, etc..
+
+       * fts.c [! _LIBC]: Include "openat.h" and "unistd--.h".
+       (HAVE_OPENAT_SUPPORT): Define.
+       [_LIBC] (fchdir): Don't undef or define; no longer used.
+       (FCHDIR): Define in terms of cwd_advance_fd rather than fchdir.
+       Now, this `function' always succeeds, and consumes its file descriptor
+       parameter -- so callers must not close such FDs.  Update callers.
+       (diropen_fd, opendirat, cwd_advance_fd): New functions.
+       (diropen): Add parameter, SP.  Adjust all callers.
+       Implement using diropen_fd, rather than open.
+       (fts_open): Initialize new member, fts_cwd_fd.
+       Remove fts_rft-setting code.
+       (fts_close): Close fts_cwd_fd, if necessary.
+       (__opendir2): Define in terms of opendir or opendirat,
+       depending on whether the FST_NOCHDIR flag is set.
+       (fts_build): Since fts_safe_changedir consumes its FD, and since
+       this code must do `closedir(dirp)', dup the dirfd(dirp) argument,
+       and close the dup'd file descriptor upon failure.
+       (fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat.
+       (fts_safe_changedir): Tweak semantics to reflect that this function
+       now calls cwd_advance_fd and hence consumes its FD argument.
+       * fts_.h [struct FTS] (fts_cwd_fd): New member.
+       [struct FTS] (fts_rft): Remove now-unused member.
+       [struct FTS] (fts_cycle.state): Improve comment.

        * stdint_.h: Remove useless parentheses in cpp directives, so that
