+       Fix conflict between two instantiations of module 'unistd'.
+       * gnulib-tool (func_emit_autoconf_snippet): Substitute
+       ${include_guard_prefix} also in the autoconf snippet.
+       * m4/getopt.m4 (gl_FUNC_GETOPT_POSIX): Don't set GNULIB_UNISTD_H_GETOPT.
+       * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Don't initialize
+       GNULIB_UNISTD_H_GETOPT.
+       * modules/getopt-posix (configure.ac): Set the
+       GNULIB_${gl_include_guard_prefix}_UNISTD_H_GETOPT variable.
+       * modules/getopt-gnu (configure.ac): Likewise.
+       * modules/unistd (Makefile.am): Change the substitution value of
+       GNULIB_UNISTD_H_GETOPT to depend on the include guard prefix.
+       Reported by Simon Josefsson.

+
+       pagealign_alloc: Doc and comments.
+       * doc/posix-functions/posix_memalign.texi: Refer to the pagealign_alloc
+       module.
+       * lib/pagealign_alloc.c (pagealign_alloc): Add comment.

+
+       test-update-copyright.sh: avoid false-positive failure
+       * tests/test-update-copyright.sh: Use $TMP.? (not $TMP.*), to work
+       around false positive failure on Cygwin/Windows.  The latter was
+       matching erroneously-created files with names like
+       update-copyright.test-ex.4.bak.  Reported by Simon Josefsson.

+
+       valgrind-tests.m4: Avoid breakage if valgrind on bash fails.
+       * m4/valgrind-tests.m4: Check that the parameters that will be
+       used works, not just a subset of them.  Reported by Bruno Haible
+       <bruno@clisp.org>.

+
+       test-stdalign.c: comment out long double tests
+       * tests/test-stdalign.c: Don't try to reduce alignment of long double
+       variables.  That provokes errors like this from gcc-4.7.0 20111124:
+       error: '_Alignas' specifiers cannot reduce alignment of \
+       'static_longdouble_alignas'.

+2011-11-22  Jim Meyering  <meyering@redhat.com>
+
+       init.sh: make "compare /dev/null FILE" output more readable
+       * tests/init.sh (compare_): Document the preferred order of arguments.
+       (emit_diff_u_header_): New function.
+       (compare_dev_null_): Emit a simulated diff, rather than just the
+       contents of the unexpected file.  Suggestion from Bruno Haible.

+
+       init.sh: work around OSF/1 5.1's mishandling of /dev/null
+       * tests/init.sh: Make our compare function slightly more portable.
