d9cf99b6a5 multistart: use b4_accept instead of action post-processing 
For each start symbol, generate a parsing function with a richer
return value than the usual of yyparse.  Reserve a place for the
returned semantic value, in order to avoid having to pass a pointer as
argument to "return" that value.  This also makes the call to the
parsing function independent of whether a given start-symbol is typed.

For instance, if the grammar file contains:

    %type <int> expression
    %start input expression

(so "input" is valueless) we get

    typedef struct
    {
      int yystatus;
    } yyparse_input_t;

    yyparse_input_t yyparse_input (void);

    typedef struct
    {
      int yyvalue;
      int yystatus;
    } yyparse_expression_t;

    yyparse_expression_t yyparse_expression (void);

This commit also changes the implementation of the parser termination:
when there are multiple start symbols, it is the initial rules that
explicitly YYACCEPT.  They do that after having exported the
start-symbol's value (if it is typed):

  switch (yyn)
    {
  case 1: /* $accept: YY_EXPRESSION expression $end  */
  { ((*yyvalue).TOK_expression) = (yyvsp[-1].TOK_expression); YYACCEPT; }
    break;

  case 2: /* $accept: YY_INPUT input $end  */
  { YYACCEPT; }
    break;

I have tried several ways to deal with termination, and this is the
one that appears the best one to me.  It is also the most natural.

* src/reader.c (grammar_rule_check_and_complete): Generate the actions
of the rules for each start symbol.

5855da4722 parser: keep string aliases as the user wrote it 
Currently our scanner decodes all the escapes in the strings, and we
later reescape the strings when we emit them.

This is troublesome, as we do not respect the user input.  For
instance, when the user writes in UTF-8, we destroy her string when we
write it back.  And this shows everywhere: in the reports we show the
escaped string instead of the actual alias:

    0 $accept: . exp $end
    1 exp: . exp "\342\212\225" exp
    2    | . exp "+" exp
    3    | . exp "+" exp
    4    | . "number"
    5    | . "\303\221\303\271\341\271\203\303\251\342\204\235\303\264"

    "number"                                                    shift, and go to state 1
    "\303\221\303\271\341\271\203\303\251\342\204\235\303\264"  shift, and go to state 2

This commit preserves the user's exact spelling of the string aliases,
instead of interpreting the escapes and then reescaping.  The report
now shows:

    0 $accept: . exp $end
    1 exp: . exp "⊕" exp
    2    | . exp "+" exp
    3    | . exp "+" exp
    4    | . "number"
    5    | . "Ñùṃéℝô"

    "number"          shift, and go to state 1
    "Ñùṃéℝô"  shift, and go to state 2

Likewise, the XML (and therefore HTML) outputs are fixed.

* src/scan-gram.l (STRING, TSTRING): Do not interpret the escapes in
the resulting string.
* src/parse-gram.y (unquote, parser_init, parser_free, unquote_free)
(handle_defines, handle_language, obstack_for_unquote): New.
Use them to unquote where needed.
* tests/regression.at, tests/report.at: Update.

d2acc4b401 cex: rename -Wcounterexample as -Wcounterexamples, and support -Wcex 
Plural vs. singular is always a problem...

But we already have conflicts-sr and conflicts-rr, so counterexamples
makes more sense than counterexample.  Besides, -Wcounterexample will
still be accepted as an unambiguous prefix of -Wcounterexamples.

Add -Wcex as a convenient alias.

While at it, use only "counterexample", never "counter example".

* src/complain.h, src/complain.c
(Wcounterexample, warning_counterexample): Rename as...
(Wcounterexamples, warning_counterexamples): these.
(argmatch_warning_docs): Rename -Wcounterexample as -Wcounterexamples.

8228d96d33 reader: reduce the "scope" of global variables 
We have too many global variables, adding structure would help.  For a

* src/scan-gram.c: here.
* src/scan-gram.h (gram_in, gram__flex_debug): Remove, make them

7fec997ecf closure: initialize it once for all 
The memory allocated by 'closure' (and some data such as 'fderives')
is used to computed a state's full itemset from its core.  This is
needed during the construction of the LR(0) automaton, and the memory
is reclaimed immediately afterwards.

Unfortunately the reports (graph, text, xml) also need this
information when describing the states with their full itemsets.  As a
consequence the memory was allocated again, fderives computed again
too, and more --trace reports are generated which only duplicate what
was already reported.

Stop that.  It does mean that we release the memory later (hence the
peak memory usage is higher now), but I don't think that's a problem
today.

* src/lr0.c (generate_states): Don't call closure_free.
* src/state.c (states_free): Do it here.
(for symmetry with closure_new which is called in generate_states).
* src/print-graph.c, src/print-xml.c, src/print.c: You can now expect
the closure module to be functional.

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.
* tests/input.at (Invalid options): Add more corner cases.

cc2235ace2 warnings: introduce -Wprecedence 
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).

e8f7155d98 grammar: record used associativity and print useless ones 
Record which symbol associativity is used, and display useless ones.

* src/symtab.h, src/symtab.c (register_assoc, print_assoc_warnings): New
* src/symtab.c (init_assoc, is_assoc_used): New
* src/main.c: Use print_assoc_warnings
* src/conflicts.c: Use register_assoc
* tests/conflicts.at (Useless associativity warning): New.

Due to the new warning, many tests had to be updated.

* tests/conflicts.at tests/existing.at tests/regression.at:
Add the associativity warning in the expected results.
* tests/java.at: Fix the java calculator's grammar to remove a useless
associativity.
* doc/bison.texi (mfcalc example): Fix associativity to remove
warning.

284bc49c83 grammar: warn about unused precedence for symbols 
Symbols with precedence but no associativity, and whose precedence is
never used, can be declared with %token instead.  The used precedence
relationships are recorded and a warning about useless ones is issued.

* src/conflicts.c (resolve_sr_conflict): Record precedence relation.
* src/symtab.c, src/symtab.h (prec_nodes, init_prec_nodes)
(symgraphlink_new, register_precedence_second_symbol)
(print_precedence_warnings): New.
Record relationships in a graph and warn about useless ones.
* src/main.c (main): Print precedence warnings.
* tests/conflicts.at: New.

697a8022c6 warnings: fix early exit of warnings treated as errors 
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.
