+ Remove uses of 'short int' and 'unsigned short int'. This raises

+
+ * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
+
+2004-10-28 Akim Demaille <akim@epita.fr>,
+ Alexandre Duret-Lutz <adl@gnu.org>
+
+ * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
+ changes.
+ (YYCDEBUG): Adjust.
+ Use it instead of cdebug_.
+ (Parser::debug_stream, Parser::set_debug_stream): New.
+ (Parser::symprint_): Define cdebug_ for temporary backward
+ compatibility.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
+ debug_stream ().
+
+2004-11-17 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
+ * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
+ * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

+
+ * data/glr.c (yyloc_default): Remove; not used.
+ Problem reported by Frank Heckenbach.
+
+2004-10-25 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c (YYRHSLOC): Move its definition next to its uses.
+ Introduce another definition to address simple location arrays.
+ (yyGLRStack): New member: yyerror_range.
+ (yyrecoverSyntaxError, yyparse): Update it.
+ (yyrecoverSyntaxError): Use it when shifting the error token to
+ have an accurate range, equivalent to the one computed by both
+ yacc.c and lalr1.cc.
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
+ that column numbers start at column 0, as per GNU Coding
+ Standards, the others tests, and the doc.
+ (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
+ Adjust to the above change (first column is 0).
+ And adjust the location of the "<error>", now covering the whole
+ line.
+
+2004-10-22 Akim Demaille <akim@epita.fr>
+ and Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove some arbitrary limits on goto numbers and relations.
+ * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
+ initial values, since they're never used.
+ (set_goto_map): ngotos is now unsigned, so test for overflow
+ by seeing whether it wraps around to zero.
+ * src/lalr.h (goto_number): Now size_t, not short int.
+ (GOTO_NUMBER_MAXIMUM): Remove.
+ * src/relation.c (relation_print, traverse, relation_transpose):
+ Check for END_NODE rather than looking at sign.
+ * src/relation.h (END_NODE): New macro.
+ (relation_node): Now size_t, not short int.
+
+2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Language and Grammar): In example, "int" is a
+ keyword, not an identifier. Problem reported by Baron Schwartz in
+ <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
+
+2004-10-11 Akim Demaille <akim@epita.fr>
+
+ * src/symtab.c (symbol_check_alias_consistency): Also check
+ 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.
