+2004-12-21  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (parser::parse): Return a bool instead of an int.
+
+2004-12-21  Akim Demaille  <akim@epita.fr>
+
+	Don't impose std::string for filenames.
+
+	* data/lalr1.cc (b4_filename_type): New.
+	(position::filename): Use it.
+	(parser.hh): Move the inclusion of stack.hh and location.hh below
+	the user code, so that needed headers for the filename type can be
+	included first.
+	Forward declare them before the user code.
+	* tests/Makefile.am (check-local, installcheck-local): Pass
+	TESTSUITEFLAGS to the TESTSUITE.
+
+2004-12-20  Akim Demaille  <akim@epita.fr>
+
+	Use more STL like names: my_class instead of MyClass.
+
+	* data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
+	(SemanticStack, SemanticType, StateStack, StateType)
+	(TokenNumberType, Stack, Slice, Traits, Parser::location)
+	(Parser::value): Rename as...
+	(location_stack, location_type, rhs_number_type, semantic_stack)
+	(semantic_type, state_stack, state_type, token_number_type, stack)
+	(slice, traits, parser::yylloc, parser::yylval): these.
+
+	* tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
+
+2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
+	* data/yacc.c (YYLLOC_DEFAULT): Likewise.
+
+2004-12-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Remove uses of 'short int' and 'unsigned short int'.  This raises
+	some arbitrary limits.  It uses more memory but nowadays that's
+	not much of an issue.
+
+	This change does not affect the generated parsers; that's a different
+	task, as some users will want to conserve memory there.
+
+	Ideally we should use size_t to represent all object counts, and
+	something like ptrdiff_t to represent signed differences of object
+	counts; but that will require more code-cleanup than I have the
+	time to do right now.
+
+	* src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
+	Use size_t, not int or short int, to count objects.
+	* src/closure.c (nritemset, closure): Likewise.
+	* src/closure.h (nritemset, closure): Likewise.
+	* src/nullable.c (nullable_compute): Likewise.
+	* src/print.c (print_core): Likewise.
+	* src/print_graph.c (print_core): Likewise.
+	* src/state.c (state_compare, state_hash): Likewise.
+	* src/state.h (struct state): Likewise.
+	* src/tables.c (default_goto, goto_actions): Likewise.
+
+	* src/gram.h (rule_number, rule): Use int, not short int.
+	* src/output.c (prepare_rules): Likewise.
+	* src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
+	errs, reductions): Likewise.
+	* src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
+	Likewise.
+	* src/tables.c (vector_number, tally, action_number,
+	ACTION_NUMBER_MINIMUM): Likewise.
+	* src/output.c (muscle_insert_short_int_table): Remove.
+
+2004-12-17  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Extensive Doxygenation.
+	(error_): Rename as...
+	(error): this, since it is visible to the user.
+	Adjust callers.
+	(Parser::message): Now an automatic variable from...
+	(Parser::yyreport_syntax_error_): here.
+	* tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
+	Parser::error.
+	* tests/input.at: Escape $.
+
+2004-12-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
+	Parenthesize rhs to avoid obscure problems with mistakes like
+	"foo$$bar = foo$1bar;".  Problem reported by twlevo at xs4all.
+	* data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
+	b4_rhs_location): Likewise.
+	* data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
+	b4_rhs_location): Likewise.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
+	yacc.c: be sure to stay within yycheck_.
+	* tests/actions.at: Re-enable C++ tests.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+
+	* src/print_graph.c (print_graph): Remove layoutalgorithm uses for
+	real.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+
+	Use #define to handle the %name-prefix.
+
+	* data/glr.c, data/yacc.c: Comment changes.
+	* data/lalr1.cc (yylex): Use #define to select the name of yylex,
+	so that one can refer to yylex in the parser file, and have it
+	renamed, as is the case with other skeletons.
+
 2004-12-16  Akim Demaille  <akim@epita.fr>
 
 	Move lalr1.cc internals into yy*.
