+
+ 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.

+
+ raise test: Avoid a test failure on Linux/MIPS.
+ * tests/test-raise.c (main): Try raising signal 199, not 99. Needed
+ because 99 is a valid signal on Linux/MIPS.
+
+2011-10-27 Bruno Haible <bruno@clisp.org>
+
+ nonblocking tests: Fix test failure on Linux/MIPS.
+ * tests/test-nonblocking-pipe.h (PIPE_DATA_BLOCK_SIZE) [Linux/MIPS]:
+ Set to 270000.

+ * lib/utimensat.c (rpl_utimensat) [Linux/hppa]: Reject invalid tv_nsec
+ values.
+ * doc/posix-functions/utimensat.texi: Mention the problem on Linux/hppa.

+
+ maint.mk: fix a bug in sc_prohibit_stddef_without_use
+ * top/maint.mk (sc_prohibit_stddef_without_use): Don't require / *\(/
+ after symbols like NULL, size_t, etc.
+ Reported by Alfred M. Szmidt.
+
+ maint.mk: exempt ENODATA from a syntax-check rule
+ * top/maint.mk (gl_extract_significant_defines_): Also exempt ENODATA
+ from the sc_prohibit_always-defined_macros syntax-check rule.
+ Add a comment. See this for more details:

+ fts: close parent dir FD before returning from post-traversal fts_read
+ The problem: the fts-using "mkdir -p A/B; rm -rf A" would attempt to
+ unlink A, even though an FD open on A remained. This is suboptimal
+ (holding a file descriptor open longer than needed), but otherwise not
+ a problem on Unix-like kernels. However, on Cygwin with certain Novell
+ file systems, (see http://cygwin.com/ml/cygwin/2011-10/msg00365.html),
+ that represents a real problem: it causes the removal of A to fail
+ with e.g., "rm: cannot remove `A': Device or resource busy"
+
+ fts visits each directory twice and keeps a cache (fts_fd_ring) of
+ directory file descriptors. After completing the final, FTS_DP,
+ visit of a directory, RESTORE_INITIAL_CWD intended to clear the FD
+ cache, but then proceeded to add a new FD to it via the subsequent
+ FCHDIR (which calls cwd_advance_fd and i_ring_push). Before, the
+ final file descriptor would be closed only via fts_close's call to
+ fd_ring_clear. Now, it is usually closed earlier, via the final
+ FTS_DP-returning fts_read call.
+ * lib/fts.c (restore_initial_cwd): New function, converted from
+ the macro. Call fd_ring_clear *after* FCHDIR, not before it.
+ Update callers.
+ Reported by Franz Sirl via the above URL, with analysis by Eric Blake
+ in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739

+
+ readme-release: improve safety of release prep instructions.
+ * README-release: Don't git pull all branches when only master
+ is needed for the release process.
+ Run make maintainer-clean before changing trees and merging.
+ Don't try to run ./configure right after git pull in case files
+ that influence the bootstrap process have changed, move the
+ ./configure step to after running ./bootstrap.
+ Don't bootstrap "one last time"... it's the first time!
