+ maint.mk: don't maintain a second build-aux variable.
+ * maint.mk (build_aux): Removed. The maintainer-makefile module
+ depends on GNUmakefile, which already maintains a cfg.mk
+ overridable $(_build-aux) for projects with a non-standard
+ build-aux directory location, although without the $(srcdir)
+ prefix. Use that variable consistently instead of introducing a
+ second one. Adjust all call sites.

+ Add stdalign module and use it in other modules.
+ This is based on a previous proposal by Bruno Haible
+ <https://lists.gnu.org/archive/html/bug-gnulib/2011-07/msg00226.html>.
+
+ stdalign: new module
+ * doc/posix-headers/stdalign.texi, lib/stdalign.in.h, m4/stdalign.m4:
+ * modules/stdalign: New files.
+ * MODULES.html.sh (c1x_core_properties): Add stdalign.
+ * doc/gnulib.texi (Header File Substitutes): Add stdalign.
+
+ stdalign-tests: new module
+ * modules/stdalign-tests, tests/test-stdalign.c: New files.
+
+ argp: use stdalign
+ * lib/argp-parse.c: Include <stdalign.h>.
+ (alignof): Remove.
+ * modules/argp (Depends-on): Add stdalign.
+
+ crypto libraries: use stdalign
+ * lib/md4.c, lib/md5.c, lib/sha1.c, lib/sha256.c, lib/sha512.c:
+ Include <stdalign.h> and <stdint.h>. Do not include <stddef.h>.
+ Do not include <stdlib.h> twice, in md4.c.
+ (UNALIGNED_P): Simplify by using alignof. Use uintptr_t, not size_t,
+ because we are accessing a pointer's bit-pattern, not a size.
+ * modules/crypto/gc-md4 (Depends-on): Add stdalign.
+ * modules/crypto/gc-md5, modules/crypto/gc-sha1, modules/crypto/md4:
+ * modules/crypto/md5, modules/crypto/sha1, modules/crypto/sha256:
+ * modules/crypto/sha512: Likewise.
+
+ sys_socket: use stdalign, not alignof
+ * lib/sys_socket.in.h: Include <stdalign.h> instead of <alignof.h>.
+ * modules/sys_socket (Depends-on): Depend on stdalign, not alignof.
