cc050fd321 warning: avoid warnings about unreachable code 
Reported by Uxio Prego.
https://lists.gnu.org/archive/html/help-bison/2018-11/msg00031.html

We also need to move the unreachable 'goto' to a reachable place,
otherwise clang complains about the code being unreachable anyway.
See also https://bugs.llvm.org/show_bug.cgi?id=39736.

Interestingly, we don't have to apply that trick to
`#define YYCDEBUG if (false) std::cerr`, clang does not warn when the
code comes from macro expansion.

* configure.ac: Use -Wunreachable-code when supported.
* data/lalr1.cc, data/yacc.c: Pacify clang's warning about `if (0)`
by using a macro.
Another possibility was to move this statement to a reachable place.
* tests/actions.at, tests/c++.at: Avoid generating unreachable code.

4fd1fc70e0 examples: ship them 
Currently, the examples are extracted on the user's side.
Unfortunately, that requires that the user has Perl, which is
otherwise not needed for Bison.  Let's ship the examples instead.

The examples were handled this way so that we could depend on
configure flags: if --enable-gcc-warnings is passed, it is understood
as "I'm a maintainer", so the examples are generated with `#line`s.
Regular users should not see them, so they are now unconditionally
removed when rolling a tarball.

Reported by Mike Frysinger.
https://lists.gnu.org/archive/html/bison-patches/2015-04/msg00000.html

* examples/local.mk: Ship all the extracted files.

* m4/cxx.m4 (BISON_CXX_WORKS): Define to true/false instead of

01898726e2 generate the default semantic action 
Currently, in C, the default semantic action is implemented by being
always run before running the actual user semantic action.  As a
consequence, when the user action is run, $$ is already set as $1.

In C++ with variants, we don't do that, since we cannot manipulate the
semantic value without knowing its exact type.  When variants are
enabled, the only guarantee is that $$ is default contructed and ready
to the used.

Some users still would like the default action to be run with
variants.  Frank Heckenbach's parser in
C++17 (http://lists.gnu.org/archive/html/bug-bison/2018-04/msg00011.html)
provides this feature, but relying on std::variant's dynamic typing,
which we forbid in lalr1.cc.

The simplest seems to be actually generating the default semantic
action (in all languages/skeletons).  This makes the pre-action (that
sets $$ to $1) useless.  But...  maybe some users depend on this, in
spite of the comments that clearly warn againt this.  So let's not
turn this off just yet.

* src/reader.c (grammar_rule_check_and_complete): Rename as...
(grammar_rule_check_and_complete): this.
Install the default semantic action when applicable.
* examples/variant-11.yy, examples/variant.yy, tests/calc.at:

f19ecae3b2 lalr1.cc: support move semantics 
Modern C++ (i.e., C++11 and later) introduced "move only" types: types such
as std::unique_ptr<T> that can never be duplicated.  They must never be
copied (by assignments and constructors), they must be "moved".  The
implementation of lalr1.cc used to copy symbols (including their semantic
values).  This commit ensures that values are only moved in modern C++, yet
remain compatible with C++98/C++03.

Suggested by Frank Heckenbach, who provided a full implementation on
top of C++17's std::variant.
See http://lists.gnu.org/archive/html/bug-bison/2018-03/msg00002.html,
and https://lists.gnu.org/archive/html/bison-patches/2018-04/msg00002.html.

Symbols (terminal/non terminal) are handled by several functions that used
to take const-refs, which resulted eventually in a copy pushed on the stack.
With modern C++ (C++11 and later) the callers must use std::move, and the
callees must take their arguments as rvalue refs (foo&&).  In order to avoid
duplicating these functions to support both legacy C++ and modern C++, let's
introduce macros (YY_MOVE, YY_RVREF, etc.)  that rely on copy-semantics for
C++98/03, and move-semantics for modern C++.

That's easy for inner types, when the parser's functions pass arguments to
each other.  Functions facing the user (make_NUMBER, make_STRING, etc.)
should support both rvalue-refs (for instance to support move-only types:
make_INT (std::make_unique<int> (1))), and lvalue-refs (so that we can pass
a variable: make_INT (my_int)).  To avoid the multiplication of the
signatures (there is also the location), let's take the argument by value.

https://lists.gnu.org/archive/html/bison-patches/2018-09/msg00024.html.

b167e7ba0d package: install the examples 
Currently, we do not install the various examples extracted from the
documentation.  Let's do it, as they are useful starting points.

* configure.ac: When --enable-gcc-warnings is set, enable ENABLE_GCC_WARNINGS.
* examples/extexi: No longer issue synclines by default.
* examples/local.mk: Except if ENABLE_GCC_WARNINGS.
* examples/calc++/local.mk, examples/mfcalc/local.mk,
* examples/rpcalc/local.mk: Install the example files.

* configure.ac: Require Automake 1.14.
* examples/calc++/local.mk, examples/local.mk, examples/mfcalc/local.mk,
* examples/rpcalc/local.mk, tests/local.mk: Use %D% and %C%.

* examples/calc++/local.mk (examples/calc++/calc++):
Build if FLEX_CXX_WORKS, not BISON_CXX_WORKS.
