The new warning category "precedence" flags useless precedence and
associativity. -Wprecedence can now be used, it is disabled by default.
The warnings about precedence and associativity are grouped into one, and
the testsuite was corrected accordingly.
* src/complain.h (warnings): Introduce "precedence".
* src/complain.c (warnings_print_categories): Adjust.
* src/getargs.c (warnings_args, warning_types): Likewise.
* src/symtab.h, src/symtab.c (print_associativity_warnings): Remove.
* src/symtab.h (register_assoc): Correct arguments.
* src/symtab.c (print_precedence_warnings): Print both warnings together.
* doc/bison.texi (Bison options): Document the warnings and provide an
example.
* tests/conflicts.at, tests/existing.at, tests/local.at,
* tests/regression.at: Adapt the testsuite for the new category
(-Wprecedence instead of -Wother where appropriate).
* origin/maint:
misc: pacify the Tiny C Compiler
cpp: make the check of Flex version portable

c++: support wide strings for file names
doc: document carets
tests: enhance existing tests with carets

Treating warnings as errors caused Bison to exit earlier than needed, making it
hide warnings that would have been printed had -Werror not been set.
Also, fix a bug that caused some context information of errors to not be
shown.
* src/complain.c (complaint_issued): Rename as...
(complaint_status): This, and change its type from boolean to
* src/complain.h (err_status): This, new enumeration.
* src/main.c (main): Adjust (only finish early if an actual complaint was
risen, not a mere warning treated an error).
* src/reader.c: Adjust.
Because argv[0] is never used, shift it out from the argument list.
* src/complain.c (complain_args): Here.
* src/scan-skel.l (at_complain): Adjust argv and argc.

* TODO: Address the issue, so remove it.
* data/bison.m4: Use b4_error with [[note]] rather than a complain_at
for context information.
* src/complain.c (complain_args): Take an additional argument, an
indentation pointer, to allow the dispatching of context information.
* src/complain.h (complain_args): Adjust prototype.
* src/scan-skel.l (at_directive_perform): Recognize the new @note mark.
* tests/input.at: Adjust.

src/symtab.c: Adjust.

The code here was too confusing, this seems more natural.
* src/complain.c (error_message): Move the indentation check and the category
output to complains. Also, no longer take a 'warnings' argument.

Move the dispatch of variadic complains to complain.c, rather than do
it in a scanner.

Rectify a bug that introduced suffixes out of place.
* src/complainc.c (complains): Handle all three special warning bits.

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.
* src/complains.h: Adjust.
* tests/input.at: Adjust.
* NEWS: Document this change.

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.

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.

This improves readability. This is also what gcc does.
* NEWS: Document this change.
* src/complain.c (complain_at): Prefix all errors with "error: ".
(complain_at_indent, warn_at_indent): Do not prefix the context
information of errors, which are basically just indented errors.
* tests/conflicts.at, tests/glr-regression.at, tests/input.at,
tests/named-refs.at, tests/output.at, tests/push.at,
tests/regression.at, tests/skeletons.at: Apply this change.

* src/complain.h : errors_flag variable
* src/complain.c : actual stuff happens here
* src/conflits.c : differentiated SR and RR conflicts
* src/getargs.c : flags_argmatch recognizes the new -Werror format
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.
A function to print warnings categories, like -Wyacc, -Wother, etc.
* src/complain.h, src/complain.c (print_warning_categories): New function.
* src/output.c (ARRAY_CARDINALITY): Move it to file 'src/system.h'.
* src/complain.h (enum warnings): New value, 'silent', "complain"
must not display the warning type.
Forthcoming changes will use the warning categories much more often,
so shortening them will improve readability.
* src/complain.c, src/complain.h, src/conflicts.c,
* src/getargs.c, src/getargs.h, src/gram.c (enum warnings):
s/warnings_/W/g.
* bootstrap.conf (gnulib_modules): Require progname.

Skip lib/main.c for bindtextdomain and set_program_name.

This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
