ec08b369ec c++: address -Wweak-vtables warnings 
Reported by Derek Clegg
http://lists.gnu.org/archive/html/bug-bison/2019-01/msg00021.html

    aux/parser-internal.h:429:12: error: 'syntax_error' has no out-of-line virtual
         method definitions; its vtable will be emitted in every translation unit
         [-Werror,-Wweak-vtables]
       struct syntax_error : std::runtime_error

To avoid this warning, we need syntax_error to have a virtual function
defined in a compilation unit.  Let it be the destructor.  To comply
with C++98, this dtor should be 'throw()'.  Merely making YY_NOEXCEPT
be 'throw()' in C++98 triggers
errors (http://lists.gnu.org/archive/html/bug-bison/2019-01/msg00022.html),
so let's introduce YY_NOTHROW and flag only ~syntax_error with it.

Also, since we now have an explicit dtor, we need to provide an copy
ctor.

* configure.ac (warn_cxx): Add -Wweak-vtables.
* data/skeletons/c++.m4 (YY_NOTHROW): New.
(syntax_error): Declare the dtor, and define the copy ctor.
* data/skeletons/glr.cc, data/skeletons/lalr1.cc (~syntax_error):
Define.

a049509d04 c++: avoid -Wundefined-func-template warnings from clang 
Reported by Derek Clegg.
http://lists.gnu.org/archive/html/bug-bison/2019-01/msg00006.html

Clang does not like this:

    template <typename D>
    struct basic_symbol : D
    {
      basic_symbol();
    };

    struct by_type {};

    struct symbol_type : basic_symbol<by_type>
    {
      symbol_type(){}
    };

It gives:

    $ clang++-mp-7.0 -Wundefined-func-template foo.cc -c
    foo.cc:11:3: warning: instantiation of function 'basic_symbol<by_type>::basic_symbol'
                 required here, but no definition is available [-Wundefined-func-template]
      symbol_type(){}
      ^
    foo.cc:4:3: note: forward declaration of template entity is here
      basic_symbol();
      ^
    foo.cc:11:3: note: add an explicit instantiation declaration to suppress this warning
                 if 'basic_symbol<by_type>::basic_symbol' is explicitly instantiated in
                 another translation unit
      symbol_type(){}
      ^
    1 warning generated.

The same applies for the basic_symbol's destructor and `clear()`.

* configure.ac (warn_cxx): Add -Wundefined-func-template.
This triggered one failure in the test suite:
* tests/headers.at (Sane headers): here, where we check that we can
compile the generated headers in other compilation units than the
parser's.
Add a variant type to make sure that basic_symbol and symbol_type are
properly generated in this case.
* data/skeletons/c++.m4 (basic_symbol): Inline the definitions of the
destructor and of `clear` in the class definition.

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)`

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.

* data/lalr1.cc (stack_symbol_type): Add an explicit copy ctor.
We cannot rely on the explicit default implementation (`= default`)
as we support C++ 98.

2b5a27ba3d Avoid compiler warnings 
At least GCC 7.3, with -O1 or -O2 (but not -O0 or -O3) generates
warnings with -Wnull-dereference when using yyformat: it fails to see
yyformat cannot be null.

Reported by Frank Heckenbach, https://savannah.gnu.org/patch/?9620.

* configure.ac: Use -Wnull-dereference if supported.
* data/glr.c, data/lalr1.cc, data/yacc.c: Define yyformat in such
a way that GCC cannot not see that yyformat is defined.
Using `default: abort();` also addresses the issue, but forces
the inclusion of `stdlib.h`, which we avoid.

3e8d1bd053 tests: beware that clang warns about "#define private public" 
We use this trick to write some test about internal details.  But
since we use -Werror, clang++ 3.6 dies issueing a warning about it.

* configure.ac (warn_tests): Disable this warning.

a2c525b34c build: re-enable compiler warnings, and fix them 
There are warnings (-Wextra) in generated C++ code:

  ltlparse.cc: In member function 'ltlyy::parser::symbol_number_type
  ltlyy::parser::by_state::type_get() const':
  ltlparse.cc:452:33: warning: enumeral and non-enumeral type in
  conditional expression
      return state == empty_state ? empty_symbol : yystos_[state];

Reported by Alexandre Duret-Lutz.

It turns out that -Wall and -Wextra were disabled because of a stupid
typo.

* configure.ac: Fix the stupid typo.
* data/lalr1.cc, src/AnnotationList.c, src/InadequacyList.c,
* src/ielr.c, src/print.c, src/scan-code.l, src/symlist.c,
* src/symlist.h, src/symtab.c, src/tables.c, tests/actions.at,
* tests/calc.at, tests/cxx-type.at, tests/glr-regression.at,
* tests/named-refs.at, tests/torture.at:
Fix warnings, mostly issues about variables used only with assertions,
which are disabled with -DNDEBUG.

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.
