44e76d801f lalr1.cc: support compilation with disabled support for exceptions 
Reported by Brooks Moses <bmoses@google.com>
http://lists.gnu.org/archive/html/bison-patches/2018-02/msg00000.html

* data/lalr1.cc (YY_EXCEPTIONS): New.
Use it to disable try/catch clauses.

* doc/bison.texi (C++ Parser Interface): Document it.

* configure.ac (CXXFLAGS_NO_EXCEPTIONS): New.
* tests/atlocal.in: Receive it.
* tests/local.at (AT_FULL_COMPILE, AT_LANG_COMPILE):
Accept a new argument, extra compiler flags.
* tests/calc.at: Run the C++ calculator with exception support disabled.

d17dc9a8b5 C++: fix -Wdeprecated warnings

* configure.ac (warn_tests): Add -Wdeprecated.
* 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.

* src/ielr.c, src/print.c, src/scan-code.l, src/symlist.c,

* tests/named-refs.at, tests/torture.at:
Fix warnings, mostly issues about variables used only with assertions,
which are disabled with -DNDEBUG.

be6fa942ac variants: avoid type punning issue 
This is based on what is recommended by both Scott Meyers, in 'Effective
C++', and Andrei Alexandrescu and Herb Sutter in 'C++ Coding Standards'.

Use a static_cast on void* rather than directly use a reinterpret_cast,
which can have nefarious effects on objects.  However, even though following
this guideline is good practice in general, I am not quite sure how relevant
it is when applied to conversions from POD to objects.  Actually, it might
very well be the opposite: isn't this exactly what reinterpret_cast is for?
What we really want *is* to transmit the memory map as a series of bytes,
which, if I am correct, falls into the kind of "low level" hack for which
this cast is meant.

In any case, this silences the warning, which will be greatly appreciated by
anyone using variants with a compiler supporting -fstrict-aliasing.

* data/variant.hh (as): Here.
* tests/c++.at (Exception safety, C++ Variant-based Symbols, Variants):
Don't use NO_STRICT_ALIAS_CXXFLAGS (revert commit ddb9db15), as type punning
is no longer an issue.
* tests/atlocal.in, configure.ac (NO_STRICT_ALIAS_CXXFLAGS): Remove
definition.
* examples/local.mk (NO_STRICT_ALIAS_CXXFLAGS): Remove from AM_CXXFLAGS.
* doc/bison.texi: Don't mention type punning issues.

82443642d2 build: look for Perl in configure. 
Bison uses "/usr/bin/perl" or "perl" in several places, and it does
not appear to be a problem.  But, at least to make it simpler to
change PERL on the make command line, check for perl in configure.

* configure.ac (PERL): New.
* doc/Doxyfile.in, doc/Makefile.am, tests/bison.in: Use it.

a029e56f5c maint: check for dot before using it 
* configure.ac: here.

Ship the generated files, to spare the user the need for Graphviz.
