5010af94d0 portability: don't use _Pragma with ICC 
ICC defines __GNUC__ [1], but does not support GCC's _Pragma for
diagnostics.  As a matter of fact, I believe it does not support
_Pragma at all (only #pragma) [2].

adf0425d11 escape properly the file names in #line for printer/destructor 
Reported by Jannick.
http://lists.gnu.org/archive/html/bug-bison/2017-05/msg00001.html

"Amusingly" enough, we have the same problem with %defines when the
parser file name has backslashes or quotes: we generate #includes with
an incorrect C string.

* src/output.c (prepare_symbol_definitions): Escape properly the file
names before passing them to M4.
* data/bison.m4, data/lalr1.cc: Don't simply put the file name between
two quotes (that should have been strong enough a smell...), expect
the string to be properly quoted.
* tests/synclines.at: New tests to check this.

1113522acb c++: fix GCC8 warnings about uninitialized values 
In 0931d14728 I removed too many
initializations from some ctors: some were not about base ctors, but
about member variables.  In fact, more of them were missing to please
GCC 8.

While at it, generate more natural code for C++ without variant:
instead of

    template <typename Base>
    parser::basic_symbol<Base>::basic_symbol (const basic_symbol& other)
      : Base (other)
      , value ()
    {
      value = other.value
    }

generate

    template <typename Base>
    parser::basic_symbol<Base>::basic_symbol (const basic_symbol& other)
      : Base (other)
      , value (other.value)
    {}

* data/c++.m4 (basic_symbol::basic_symbol): Always initialize 'value',
it might be a POD without a ctor.
* data/lalr1.cc (stack_symbol_type::stack_symbol_type): Likewise.
* data/variant.hh (variant::variant): Default initialize the buffer too.

bd07c76b0a c++: avoid GCC 8 warnings 
GCC 8 issues warnings whose root cause was a bit hard to find.

    calc.cc: In member function 'virtual int yy::parser::parse()':
    calc.cc:810:18: warning: '*((void*)&<anonymous> +8)' may be used uninitialized in this function [-Wmaybe-uninitialized]
         , location (l)
                      ^
    calc.cc: In member function 'void yy::parser::yypush_(const char*, yy::parser::stack_symbol_type&)':
    calc.cc:810:18: warning: '*((void*)&<anonymous> +8)' may be used uninitialized in this function [-Wmaybe-uninitialized]
         , location (l)
                      ^
    calc.cc: In member function 'void yy::parser::yypush_(const char*, yy::parser::state_type, yy::parser::symbol_type&)':
    calc.cc:810:18: warning: '*((void*)&<anonymous> +8)' may be used uninitialized in this function [-Wmaybe-uninitialized]
         , location (l)
                      ^

The problem is with locations that don't have a constructor, such as
Span (in calc.cc) which is POD.  It is POD on purpose: so that we can
use that structure to test glr.cc which cannot use non POD in its
(C) stacks.

* data/c++.m4 (basic_symbol): Also ensure that 'location' is
initialized.

7ab25ad020 C++: remove useless copy-constructor 
We currently generate copy constructors such as the following
one (taken from examples/variant.yy):

    parser::stack_symbol_type::stack_symbol_type (const stack_symbol_type& that)
      : super_type (that.state, that.location)
    {
      switch (that.type_get ())
      {
        case 3: // TEXT
        case 8: // item
          value.copy< ::std::string > (that.value);
          break;

        case 7: // list
          value.copy< ::std::vector<std::string> > (that.value);
          break;

        case 4: // NUMBER
          value.copy< int > (that.value);
          break;

        default:
          break;
      }
    }

they are actually useless: we never need it.

5952fe5abf glr: fix improperly placed synclines 
Predicates with GLR are issued with synclines in the middle of C code:

          case 2:
      if (! (#line 6 "sempred.y" /* glr.c:816  */
      new_syntax)) YYERROR;
    #line 793 "sempred.tab.c" /* glr.c:816  */

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.

476c1cca59 lalr1, yacc: use the default location as initial error location 
Currently lalr1.cc makes an out-of-bound access when trying to read @1
in rules with an empty rhs (i.e., when there is no @1) that raises an
error (YYERROR).

glr.c already gracefully handles this by using @$ as initial location
for the errors.  Let's do that in yacc.c and lalr1.cc.

573654ca9e c++: reserve 200 slots in the parser's stack 
This is consistent with what is done with yacc.c and glr.c.  Because
it also avoids that the stack needs to be resized very soon, it should
help keeping tests about destructors more reliable.

Indeed, if the stack is created too small, very soon the C++ library
needs to enlarge it, which means creating a new one, copying the
elements from the initial one onto it, and then destroy the elements
of the initial stack: that would be a spurious call to a destructor.

821394a3c8 c++: symbols can be empty, so use it 
The previous patches ensure that symbols (symbol_type and
stack_symbol_type) can be empty, cleared, and their emptiness can be
checked.  Therefore, yyempty, which codes whether yyla is empty or
not, is now useless.

In C skeletons (e.g., yacc.c), the fact that the lookahead is empty is
coded by "yychar = YYEMPTY", which is exactly what this patch
restores, since yychar/yytoken corresponds to yyla.type.

* data/lalr1.cc (yyempty): Remove.
Rather, depend on yyla.empty ().

ee2f433512 c++: provide a means to clear symbols 
The symbol destructor is currently the only means to clear a symbol.
Unfortunately during error recovery we might have to clear the
lookahead, which is a local variable (yyla) that has not yet reached
its end of scope.

Rather that duplicating the code to destroy a symbol, or rather than
destroying and recreating yyla, let's provide a means to clear a
symbol.

827bc59ca1 %union: fix the support for named %union 
Bison supports a union tag, for obscure reasons.  But it does a poor
job at it, especially since Bison 3.0.
Reported by Stephen Cameron and Tobias Frost.

It did not ensure that the name was not given several times.  An easy
way to do this is to make the %union tag be handled as a %define
variable, as they cannot be defined several times.

Since Bison 3.0, the synclines were wrongly placed, resulting in
invalid code.  Addressing this issue, because of the way the union tag
was stored (as a code muscle), would have been tedious.  Unless we
rather define the %union tag as a %percent variable, whose synclines
are easier to manipulate.

So replace the b4_union_name muscle by the api.value.union.name
%define variable, document, and check.

* data/bison.m4: Make sure that api.value.union.name has a keyword value.
* data/c++.m4: Make sure that api.value.union.name is not defined.
* data/c.m4 (b4_union_name): No longer use it, use api.value.union.name.
* doc/bison.texi (%define Summary): Document it.
* src/parse-gram.y (union_name): No longer define b4_uion_name, but
api.value.union.name.
* tests/input.at (Redefined %union name): New.
* tests/synclines.at (%union name syncline): New.
* tests/types.at: Check named %unions.

8d4dc896cb yacc.c: fix broken union when api.value.type=union and %defines are used 
Reported by Rich Wilson.

* data/c.m4 (b4_symbol_type_register): Append to b4_union_members,
not b4_user_union_members.
The latter invokes the former, but it is the former which is reinitialized
to empty by b4_value_type_setup_union.
* tests/types.at: Check it.

This reveals another bug, this time in the case of glr.c parsers.

* data/glr.c: Generate the header file before the implementation file,
to be sure that the setup is run before what depends on it.
