(string_as_id): Quote $1 before using it as a key, since the
lexer no longer quotes it for us.
(string_content): Don't strip quotes, since lexer no longer
quotes it for us.
* src/scan-gram.l: Include quotearg.h.
("\""): Omit quote.
("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
a key, since the rest of the lexer doesn't quote it.
* src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
* tests/regression.at (Token definitions): Check for backslashes
in token strings.
escaped_file_name_output, since we now use it for symbol tags as
well. All uses changed.
(symbol_destructors_output, symbol_printers_output):
Escape symbol tags too.
Problem reported by Matyas Forstner in
<http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
* src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
not needed.
* src/output.c (user_actions_output, token_definitions_output,
symbol_destructors_output, symbol_printers_output): Likewise.
* src/reader.c (prologue_augment): Likewise.

All uses changed.
(N_STRETCH): Rename from N_EXPAND. All uses changed.
Relation sizes are of type relation_node, not size_t (this is
merely a doc fix, since the two types are equivalent).
(relation_transpose): Relation sizes are of type relation_node,
not int.
(top, infinity): Now of type relation_node, not int.
(traverse, relation_transpose): Use relation_node, not int.
Relation sizes are of type relation_node, not size_t (this is

(relation_transpose): Relation sizes are of type relation_node,
not int.
changed to use xcalloc, xnmalloc, xnrealloc, respectively,
unless otherwise specified below.
* src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
to allocate kernel_base, kernel_items, kernel_size, since
they needn't be initialized to 0.
(allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
* src/closure.c (new_closure): Likewise, for itemset.
* src/derives.c (derives_compute): Likewise, for delts, derives, q.

conflict_list.
(save_column): Likewise for froms[symno], tos[symno].
(goto_actions): Likewise for state_count.
(pack_table): Likewise for base, pos, check.
(tables_generate): Likewise for width.
* src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
for initial core. Just have a separate core, so we needn't worry
about whether kernel_size and kernel_base are initialized.
* src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
kernel_size, kernel_items): Remove unnecessary initialization.

conflrow, conflict_table, conflict_list, table, check):
Likewise.
* src/closure.c (new_closure): Arg is of type unsigned int, not int.
This is because all callers pass unsigned int.
* src/closure.h (new_closure): Likewise.
* src/lalr.c (initialize_F): Initialize reads[i] in all cases.
(build_relations): Initialize includes[i] in all cases.
* src/reader.c (packgram): Always initialize rules[ruleno].prec
and rules[ruleno].precsym. Initialize members in order.
* src/relation.c (relation_transpose): Always initialize new_R[i]
and end_R[i].
* src/table.c (conflict_row): Initialize 0 at end of conflict_list.
* src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
conflict_list[0] was always 0, but now it isn't initialized.
* src/table.c (table_grow): When conflict_table grew, the grown
area wasn't cleared. Fix this.

(set_states): Don't reuse kernel_size and kernel_base

about whether kernel_size and kernel_base are initialized.
(shift_symbol, redset, shiftset, kernel_base,
kernel_size, kernel_items): Remove unnecessary initialization.
GOTO_NUMBER_MAXIMUM, since we occasionally compute
ngotos + 1 without checking for overflow.
(build_relations): Use END_NODE, not -1, to denote end of edges.
(set_goto_map, map_goto, initialize_F, add_loopback_edge,
build_relations): Use goto_number, not int, for goto numbers.
type names, destructors, and printers.
Reported by Alexandre Duret-Lutz.
Recode the handling of associativity and precedence in terms
of symbol_precedence_set.
Accept no redeclaration at all, not even equal to the previous
value.
(redeclaration): New.
Use it to factor redeclaration complaints.
(symbol_make_alias): Don't set the type of the alias, let
symbol_check_alias_consistency do it as for other features.
* src/symtab.h (symbol): Add new member prec_location, and
type_location.
* src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
* tests/input.at (Incompatible Aliases): New.
Define when we know YYLTYPE's structure, i.e., when the default
YYLLOC_DEFAULT is used.
* data/c.m4 (b4_yysymprint_generate): Use it.
* data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
value of the result.
(error_start_): Replace with...
(error_range_): this location array.
This allows to replace code relying on the implementation of
locations by portable code.
* data/yacc.c (yylerrsp): Replace with...
(yyerror_range): this.
Every time a token is popped, update yyerror_range[0], to have an
accurate location for the error token.
* data/glr.c (YY_LOCATION_PRINT): New.
(yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
deference a pointer.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
report the location in %printers.
* src/scan-skel.l: Instead of abort, report error messages to ease
understanding skeleton scanning failures.
