This line doesn't add any meaningful information anymore, the appended
[-Werror=CATEGORY] is enough. It is actually more insightful, as it
allows to distinguish warnings treated as errors from those that
aren't. This line is also removed by gcc 4.8.
* src/complain.c (set_warnings_issued): The only action left was
checking if the error bit corresponding to the warning issued was set,
and that function was only called once. Therefore, remove it, and do
its job directly in the caller...
(complains): here.

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

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.

This is the continuation of the work on the readability of errors
context.
For example, what used to be:
input.y:5.10-24: %printer redeclaration for <field2>
input.y:3.11-25: previous declaration
is now:
input.y:5.10-24: %printer redeclaration for <field2>
input.y:3.11-25: previous declaration
* NEWS: Document this change.
* src/symtab.c (symbol_redeclaration, semantic_type_redeclaration,
user_token_number_redeclaration, default_tagged_destructor_set,
default_tagless_destructor_set, default_tagged_printer_set,
default_tagless_printer_set): Use complain_at_indent to
output with increased indentation level.
* tests/input.at: Apply this change.

The current routines used to display s/r and r/r conflicts are both
inconvenient from the programmer point of view (they do not use the
warning infrastructure) and for the user (the messages are rather
terse, not necessarily pleasant to read, and because they don't use
the same routines, they look different).
It was due to the belief (dating back to the initial checked-in
version of Bison) that, at some point, POSIX Yacc mandated the format
for these messages. Today, the Open Group's manual page for Yacc,
<http://pubs.opengroup.org/onlinepubs/009695399/utilities/yacc.html>,
explicitly states that the format of these messages is unspecified.
See commit be7280480c and
<http://lists.gnu.org/archive/html/bison-patches/2002-12/msg00027.html>.
For a discussion on the chosen warning format, see
http://lists.gnu.org/archive/html/bison-patches/2012-09/msg00039.html
In an effort to factor the handling of errors and warnings, use the
Bison warning routines to report these messages.
* src/conflicts.c (conflicts_print): Rewrite with clearer sections
about S/R and then R/R conflicts.
(conflict_report): Remove, inlined in its sole
caller...

* NEWS: Update.
When no header was to be generated, Bison would issue:
/* In a future release of Bison, this section will be replaced
by #include "". */
#ifndef YY_
# define YY_
It now properly generates nothing.
* data/c.m4 (b4_cpp_guard_open, b4_cpp_guard_close): Issue nothing when
the file name is empty.

to generate.

in GLR mode, regardless of the number of reduce/reduce conflicts.

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

When it is not given, define the position and location classes instead
of including their headers.

scan-code.l is already passing argument to b4_dollar_dollar for the
