bd0cf11e00 c++: always issue the "generated by" message

(b4_copyright): Use it.
* data/location.cc, data/stack.hh: Use it too, for the stub files
(position.hh and stack.hh).

ea31f21fd8 C++: let %require "3.2" disable the generation of obsolete files 
The files stack.hh and position.hh are deprecated.  Rather than
devoting specify %define variables to discard them (api.position.file
and api.stack.file), and rather than having to use special rules when
api.location.file is used, let's simply decide that from %require
"3.2" onwards, these files will not be generated.

The only noticeable thing here is that, in order to be able to check
the behavior of %require "3.2", to have this version (which is still
3.1-*) to accept %require "3.2".

* src/gram.h, src/gram.c (required_version): New.
* src/parse-gram.y (version_check): Set it.
* src/output.c (prepare): Pass it m4.
* data/bison.m4 (b4_required_version_if): Receive it and use it.
* data/location.cc, data/stack.hh: Replace the api.*.file with only
required version comparison.
* tests/input.at: No longer check api.stack.file and api.position.file.
* NEWS, doc/bison.texi: Don't mention them.
Document the %require 3.2 behavior.
* tests/output.at: Use %require 3.2 instead.

b8351d06f1 C++: issue a better CPP guard and Doxygen file command 
Currently we use "<dir><api.location.file>" as \file argument, and as
base for the CPP guard.  This is not nice when <dir> is absolute, in
which case it is expected that the user will use api.location.include
to get something nicer.  If defined, use that name instead.

* data/location.cc (b4_location_path): New.
Use it.
* tests/c++.at (Shared locations): Check the guard and Doxygen doc.

5fe636c7ee c++: provide a means to control how location.hh is included 
Users may want to generate the location file elsewhere, say
$top_srcdir/include/ast/location.hh.  Yet, we should not generate
`#include "$top_srcdir/include/ast/location.hh"` but probably
something like `#include <ast/location.hh>`, or `#include
"ast/location.hh", or `#include <location.hh>`.  It entirely depends
on the compiler flags (-I/-isystem) that are used.  Bison cannot guess
what is expected, so let's give the user a means to tell how the
location file should be included.

* data/location.cc (b4_location_file): New.
* data/glr.cc, data/lalr1.cc: Use it.

50b8d4ba5a c++: support absolute api.location.file names 
In the case a user wants to create location.hh elsewhere, it can be
helpful to define api.location.file to some possibly absolute path
such as -Dapi.location.file='"$(top_srcdir)/include/ast/location.hh"'.
Currently this does not work with `-o foo/parser.cc`, as we join foo/
and $(top_srcdir) together, the latter starting with slash.

We should not try to do that in m4, manipulating file names is quite
complex when you through Windows file name in.  Let m4 delegate this
to gnulib.

* src/scan-skel.l (at_output): Accept up to two arguments.
* data/bison.m4 (b4_output): Adjust.
* tests/skeletons.at (Fatal errors but M4 continues producing output):
Adjust to keep the error.

* data/location.cc, data/stack.hh: Leave the concatenation to @output.
* tests/output.at: Exercise api.location.file with an absolute path.

3e6a075f7f c++: make position.hh completely useless 
Let's put the definition of position into location.hh, there's no real
value in keeping them separate: they are small, and share the same
requirements.

To help users transition to this new model, still generate position.hh
by default, but as a simple include to location.hh.

* data/location.cc (api.position.file): Accept only 'none' as possible
value.
(position.hh): Make it a stub.
(location.hh): Adjust.
(b4_position_define): Merge into...
(b4_location_define): this.
* data/glr.cc, data/lalr1.cc, tests/input.at, tests/output.at: Adjust.

667588ee8a c++: add support for api.position.file and api.location.file 
* data/location.cc: Sort includes.
(b4_position_file, b4_location_file): New.
When there's a file for locations but not for positions, include the
definition of position in the location file.
* data/lalr1.cc (b4_shared_declarations): Include the
position/location file when it exists.
Otherwise, define the class.
* data/glr.cc: Likewise.
* tests/input.at (%define file variables): Check them.
* tests/output.at (C++ output): Check various cases with
api.position.file and api.location.file.

f348522005 C++: fix portability issue with MSVC 2017 
Visual Studio issues a C4146 warning on '-static_cast<unsigned>(rhs)'.
The code is weird, probably to cope with INT_MIN.  Let's go back to
using std::max (whose header is still included in position.hh...) like
originally, but with the needed casts.

Reported by 長田偉伸, and with help from Rici Lake.

and commit 75ae829984.

* data/location.cc (position::add_): Take min as an int.
Use std::max.
While here, get rid of a couple of useless inlines.

Work on some other areas of Bison revealed that some macros expanded
to be expanded only once were actually expanded several times.  This

* data/lalr1.cc: Define YY_NULL in the *.cc file, it is not needed
in the header.
* data/location.cc: iosfwd suffices.

ef51bfa744 c++: use nullptr for C++11. 
C++11 introduces "nullptr" which plays the role of C's NULL, in
replacement of "0".  Fix the C++ skeletons to avoid warnings about
uses of "0" in place of "nullptr", and improve C skeletons to also use
this "nullptr" when compiled with a C++11 compiler.

* configure.ac: More C++ warnings.
* NEWS (2.5.1): Document this.
* data/c++.m4, data/c.m4 (b4_null_define): New.
(b4_null): Use YY_NULL instead of 0.
* data/glr.c, data/lalr1.cc, data/location.cc, data/yacc.c:
Call b4_null_define/b4_null where appropriate.
Use YY_NULL instead of NULL.
* data/location.cc (initialize): Accept a default argument,
YY_NULL.
* tests/actions.at, tests/calc.at: Adjust.

* data/glr.c, lib/libiberty.h, src/system.h (__attribute__):
Do not disable it when __STRICT_ANSI__ is defined, as, for
instance, it disables the __attribute__((unused)) which
protects us from some compiler warnings.
This was already done elsewhere in Bison, in 2001, see
4a0d893695.
* tests/regression.at: Adjust output.
