+
+ posix_spawn_file_actions_addchdir: New module.
+ Suggested by Eric Blake in
+ <https://lists.gnu.org/archive/html/bug-findutils/2018-09/msg00007.html>.
+ * lib/spawn.in.h (posix_spawn_file_actions_addchdir): New declaration.
+ * lib/spawn_int.h (struct __spawn_action): Add tag 'spawn_do_chdir' and
+ union member 'chdir_action'.
+ * lib/spawn_faction_addchdir.c: New file.
+ * lib/spawni.c (__spawni): Implement the spawn_do_chdir action.
+ * lib/spawn_faction_addclose.c: Test REPLACE_POSIX_SPAWN instead of
+ HAVE_WORKING_POSIX_SPAWN.
+ * lib/spawn_faction_adddup2.c: Likewise.
+ * lib/spawn_faction_addopen.c: Likewise.
+ * m4/posix_spawn_faction_addchdir.m4: New file.
+ * m4/posix_spawn.m4 (gl_POSIX_SPAWN_BODY): Test whether module
+ 'posix_spawn_file_actions_addchdir' is present and whether
+ posix_spawn_file_actions_addchdir_np exists. Define REPLACE_POSIX_SPAWN
+ instead of HAVE_WORKING_POSIX_SPAWN.
+ * m4/spawn_h.m4 (gl_SPAWN_H): Test whether
+ posix_spawn_file_actions_addchdir is declared.
+ (gl_SPAWN_H_DEFAULTS): Initialize
+ GNULIB_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
+ HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
+ REPLACE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR.
+ * modules/spawn (Makefile.am): Substitute
+ GNULIB_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
+ HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
+ REPLACE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR.
+ * modules/posix_spawn_file_actions_addchdir: New file.
+ * modules/posix_spawn_file_actions_addclose (Depends-on,
+ configure.ac): Test also REPLACE_POSIX_SPAWN.
+ * modules/posix_spawn_file_actions_adddup2 (Depends-on,
