e3fdc37049 generate the default action only for C++ 
This commit adds restrictions to what was done in
01898726e2 [1].

Rici Lake [2] has shown that it's risky to disable the pre-action, at
least now.  Also, generating the default $$ = $1 action can have bad
effects in some cases [3].

The original change [1] was prompted for C++.  Let's try it there
only, for a start.  We could restrict it further to lalr1.cc with
variants, but we need to see in the wild how this change behaves.  And
it is not unreasonable to expect grammar files in C++ to behave better
wrt types.

d03b1a7e8c getargs: use LC_MESSAGES trick only on glibc 
* src/getargs.c (usage): Rely on setlocale (LC_MESSAGES, NULL)
trick only on glibc, as POSIX does not specify the output
of setlocale in this case, and the Gnulib localename module
source code indicates that the trick works only on glibc.

30465cb778 drop unused options --raw, -n, -e, --include and -I 
* --raw appears to be ignored.  It was marked as obsolete in the
  commit ec3bc39, and documented as no longer supported as of 1.29
  (2001-09-07).  Support for %raw appears to have been dropped in
  e9955c83 on 2002-06-11, but --raw was kept around.  Maybe it's time
  to drop it as well?

* Commit e9955c83 dropped support for %no-parser as well, and
  converted it to option.  --no-parser was later dropped in 728c4be2
  on 2007-08-12, but -n was kept around, probably as an omission.  All
  three are documented as removed since 2.3b (2008-05-27).

* -e existed for a single day in 2001.  It was introduced in eeeb962b
  on 2001-11-27.  The handling was removed in c7925b99 on 2001-11-28,
  but "e" was kept in the list of short options.  Probably an
  omission.

* --include appears to be dead code.  The option sets a variable, but
  that variable is not used anywhere.  It was added in f6bd5427 on
  2001-11-26 as a %-directive, with comments that it's not yet
  implemented.  It was converted to a command-line option later, but
  doesn't seem to ever have been actually implemented.

808e523db4 diagnostics: revamp the handling of -Werror 
Recent discussions with Joel E. Denny
(http://lists.gnu.org/archive/html/bison-patches/2013-02/msg00026.html)
show that it is desirable to tell the difference between an option
that was explicitly disabled with -Wno-foo, as opposed to be left
unset.  The current framework does not allow this.

Instead of having a first int to store which options are enabled, and
another to store which are turned into errors, use an array that for
each warning category tells its status: disabled, unset, warning,
error.

* src/complain.h, src/complain.c (warning_bit): New enum.
(warnings): Use it.
(severity): New enum.
(warnings_flag): Now an array of severity.
(errors_flag): Remove, now done by warnings_flag.
(complain_init): New function, to initialie warnings_flag.
(warnings_are_errors): New Boolean, for -Werror.
* src/complain.c (warning_severity): New.
(warnings_print_categories, complains): Use it.
* src/getargs.c (warning_argmatch): Adjust to use warnings_flag.
(warnings_argmatch): Ditto.
Handle -Werror and -Wno-error here.
(getargs): Adjust.
* src/main.c (main): Call complain_init.

9a9130f26d options: no longer document warnings when diagnosing an invalid -W 
The argmatch functions accept prefixes of the alternatives (like
getopt does for long options).  Bison uses this to document the
warning categories.  This is troublesome: it duplicates the --help
documentation, it is not gettextized, it is displayed with ugly quotes
(because argmatch uses it to display the list of possible answers),
and it prevents straighforward uses of the tables of valid warning
categories (for instance so that warning diagnostics end with the name
of the warning).

The "hidden" option --trace uses the same trick, but it does not need
to be translated, nor to be described in --help.

* src/getargs.c (warnings_args): Remove pseudo documentation.
Comment changes.

e0992e5458 maint: be compilable with GCC 4.0 
The "shadows a global declaration" warning in GCC 4.0 was a bit
annoying.  It does not like that a type name be used in a prototype of
a function (not the implementation, just the declaration):

  In file included from src/LR0.c:38:
  src/reader.h:56: warning: declaration of 'named_ref' shadows a
                            global declaration
  src/named-ref.h:35: warning: shadowed declaration is here

It does not like either when a global variable name is used in a
prototype.  Flex 2.5.37 generates this prototype:

  void gram_set_debug (int debug_flag  );

* src/getargs.h, src/getargs.c (debug_flag): Rename as...

1048a1c901 errors: change output, and improve -y coherence 
The prefix of warnings treated as errors is now "error: ". Also, their
suffix now reflects the changes in the Werror option format.

An output for -Werror=other used to be:
  bison: warnings being treated as errors
  input.y:1.1: warning: stray ',' treated as white space [-Wother]

It is now:
  bison: warnings being treated as errors
  input.y:1.1: error: stray ',' treated as white space [-Werror=other]

The line "warnings being treated as errors" no longer adds any info,
it will be removed in a forthcoming change.

* NEWS: Add entry "Enhancement of the -Werror"
* doc/bison.texi: Move the warnings-as-error to a new bullet.
* src/complain.c (complains): Refactor, change the prefix of warnings
that are treated as errors.
(warnings_print_categories): Support for [-Werror=CATEGORY] display
* src/getargc.c (getargs): -y implies -Werror=yacc
* tests/input.at: Update expected --yacc output for coherence.

9503b0a4a8 errors: introduce the -Werror=CATEGORY option 
This new option is a lot more flexible than the previous one. Its
details will be discussed in the NEWS and info file, in a forthcoming
change.

If no category is specified (ie: used as simply "-Werror"), the
functionality is the same as before.

* src/complain.c (errors_flag): New variable.
(set_warning_issued): Accept warning categories as an argument.
* src/complain.h (Wall): Better definition.
* src/getargs.c (flags_argmatch): Support for the new format.
(usage): Update -Werror to -Werror[=CATEGORY] format.

* src/complain.c (errors_flag): New variable.
(set_warning_issued): Accept warning categories as an argument.
* src/complain.h (Wall): Better definition.
* src/getargs.c (flags_argmatch): Support for the new format.
(usage): Update -Werror to -Werror=[CATEGORY] format.

http://lists.gnu.org/archive/html/bug-bison/2012-08/msg00007.html
shows that it is useful to help users report translation issues.
While at it, include other informative bits that the coreutils shows.

* src/getargs.c (usage): Report more URLs where the user can
refer to.
Mostly copied/pasted from coreutils' emit_ancillary_info function.

518e88308f introduce -Wdeprecated 
GCC seems to be using "deprecated" consistently over "obsoleted", so
use -Wdeprecated rather than -Wobsolete.

* src/complain.h (warnings): Add Wdeprecated.
* src/complain.c (warnings_print_categories): Adjust.
* src/getargs.c: Likewise.
* doc/bison.texi: Document it.

* src/scan-code.l: Use this category for the trailing ';' support.
* tests/actions.at: Adjust expected output.

* data/c.m4, data/glr.c, data/yacc.c (YYID): Remove.
No longer use ARGSUSED.
* src/getargs.c: Restore simpler inclusion of getopt.h (anyway, since
then we now use gnulib which certainly protects us from such issues).
