* lib/autoconf/general.m4 (_AC_CHECK_DECL_BODY): Restore werror flags
inside the AC_CACHE_CHECK that saves them. Commit
82ef7805fa broke this. From Tom Lane
(trivial change).
* tests/semantics.at (AC_CHECK_DECLS): Test this.
* lib/autoconf/general.m4 (_AC_UNDECLARED_WARNING): New macro.
(_AC_CHECK_DECL_BODY): Call it once per language; treat warnings as
errors when its verdict indicates that.
* tests/semantics.at (AC_CHECK_DECLS): Add a macro call that relies on
the new semantics. Avoid -Wmissing-variable-declarations warnings.
* doc/autoconf.texi (Generic Declarations): Document the implications.
* NEWS: Mention this change.
Done via 'make update-copyright', since all files are effectively
modified and distributed this year via public version control.
* all files: Update copyright year.
* lib/autoconf/headers.m4 (AC_CHECK_HEADER): Use _AC_CHECK_HEADER_COMPILE
by default. Continue to use _AC_CHECK_HEADER_PREPROC if fourth arg is '-'.
(_AC_CHECK_HEADER_PREPROC): Issue a deprecation warning.
(_AC_CHECK_HEADER_MONGREL, _AC_CHECK_HEADER_MONGREL_BODY): Remove.
* tests/c.at, tests/semantics.at: Update uses of AC_CHECK_HEADER(S).
* doc/autoconf.texi, NEWS: Document change.
Done via 'make update-copyright', since all files are effectively
modified and distributed this year via public version control.

More fallout from the same 2.66 regression that was partially fixed
yesterday, but until yesterday's AS_LITERAL_IF actually treated \ as a
non-literal, apparently no one noticed the latent bug of a spurious
call to AC_CHECK_FUNC([\]) during automake's libobj5.test.
* lib/autoconf/functions.m4 (AC_REPLACE_FUNCS): Flatten newlines
and move guts...
(_AC_REPLACE_FUNCS): ...to new helper.
* tests/semantics.at (AC_REPLACE_FUNCS): Enhance test.

non-literals, which was lost in 2010-02-26 optimization.

* lib/m4sugar/m4sh.m4 (_AS_TR_SH): Also consider `*' as literal.
(_AS_TR_CPP): Likewise.
* tests/semantics.at (AC_CHECK_ALIGNOF struct): When checking
for numeric answer, be sure to not allow variable references.

building autoconf and not installed, are GPLv3.

AC_CHECK_TYPE, AC_CHECK_TYPES.
* doc/autoconf.texi (Generic types): C types must be type-names
(the C terminology), not type-ids (the C++ term). C++ types
must not be anonymous.
* lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
for C++; this drops support for anonymous struct and union types,
which were problematic anyway.
* tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
for C++.
Factor out the warning to...

cross-compiling.

that Posix has about { }. Use better quoting.
