Problems reported by Bruno Haible in:

* lib/stdalign.in.h (_Alignas):
* m4/stdalign.m4 (gl_STDALIGN_H):
Use octal, not decimal, for __HP_cc version. Perhaps HP formerly
used octal (as that is how they document it), but it is decimal in
practice now and the ancient implementations no longer matter.
* tests/test-stdalign.c (main) [__HP_cc && __ia64]: Skip test.

which cites p 150 of a manual saying that 'aligned' works on Itanium.
* lib/stdalign.in.h (_Alignas):
Assume the '061200' applies to Itanium, not to PA-RISC.
* m4/stdalign.m4 (gl_STDALIGN_H): Adjust to match stdalign.in.h.
* build-aux/gendocs.sh (version):
* doc/gendocs_template:
* doc/gendocs_template_min:
* doc/gnulib.texi:
* lib/version-etc.c (COPYRIGHT_YEAR):
Update copyright dates by hand in templates and the like.
* all files: Run 'make update-copyright'.

Problem reported by Ulrich Mueller in <http://bugs.gnu.org/14812>.
* lib/stdalign.in.h (_Alignas, _Alignof):
Port to FreeBSD 9.1, and to C11 and C++11.
(_Alignas): Also support ICC.
* lib/verify.h (_Static_assert): Undef if <stddef.h> defines it.
* m4/stdalign.m4 (gl_STDALIGN_H): Port to ICC and to C++11.
ISO C11 says that _Alignof's operand must be a parenthesized type.

<http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00960.html>.
* doc/posix-headers/stdalign.texi (stdalign.h): Document this.
* m4/stdalign.m4 (gl_STDALIGN_H): Don't use _Alignof (expr).
* m4/stdalign.m4 (gl_STDALIGN_H): Relax the _Alignof test,
as it was too strict: alignof must divide offsetof, but it need
not equal offsetof. Inspired by Joseph S. Myers's comment
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52023#c10>.
Conversely, tighten the _Alignas test a bit, as the resulting
alignment must be exactly 8.

<http://lists.gnu.org/archive/html/bug-gnulib/2011-12/msg00005.html>.
* doc/posix-headers/stdalign.texi (stdalign.h): Mention Clang 3.0,
which has <stdalign.h> but which does not define alignof.
* m4/stdalign.m4 (gl_STDALIGN_H): Check for Clang 3.0's problem.
