+
+ * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
+ Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
+ * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
+ Check for malloc failure, for consistency with yacc.c.
+ (yytname_size): Remove, for consistency with yacc.c.
+
+ The bug still remains in data/lalr1.cc, as I didn't have time
+ to fix it there.

+
+ * configure.ac (GXX): Rename as...
+ (CXX): this, to keep the original Autoconf semantics.
+ Require 2.57.
+ * data/lalr1.cc: Fix b4_copyright invocations.
+ If YYDEBUG is not defined, don't depend upon name_ being defined.
+ (location.hh): Include string and iostream.
+ (Position::filename): New member.
+ (Position::Position ()): New.
+ (operator<< (Position)): New.
+ (operator- (Position, int)): New.

+ iterator names.
+ (operator<< (Location)): New.
+ * tests/atlocal.in (CXX): New.
+ * tests/testsuite.at (AT_COMPILE_CXX): New.
+ * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
+ locations in a more synthetic way.
+ (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
+ lalr1.cc is used.
+ Adjust the C locations to match those from Emacs: first column is
+ column 0.
+ Change all the expected results.
+ Conform to the GCS: simplify the locations when applicable.
+ (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
+ (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
+ these CPP macros with the m4 macros new defined by...
+ (AT_CHECK_PUSHDEFS): this, i.e.:
+ (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)

+
+ * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
+ Location as is defined.

+ "s" to stand for a non-state.
+
+2003-02-02 Akim Demaille <akim@epita.fr>
+

+
+2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
+
+ * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
+ of $1.
+
+ Changes in response to error report by S. Eken: GLR mode does not
+ handle negative $ indices or $ indices in embedded rules correctly.
+ See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
+
+ * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
+ (b4_rhs_location): Ditto.
+ (yyfill): New function to copy from stack tree into array
+ incrementally.
+ (yyuserAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ Define YYFILL to use in user-defined actions to fill semantic array
+ as needed.
+ Remove dummy use of yystack, as there is now a guaranteed use.
+ (yydoAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ (yyresolveAction): Ditto.
+ (yyglrShiftDefer): Update comment.
+ (yyresolveStates): Use X == NULL for pointers, not !X.
+ (yyglrReduce): Ditto.
+ (yydoAction): Ditto
+
+ * tests/glr-regr1.at: Rename to ...
+ * tests/glr-regression.at: Add new regression test for the problems
+ described above (adapted from S. Eken).
+ Update copyright notice.
+ * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
+ * tests/Makefile.am: Ditto.
+
+2003-01-28 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc: Do not use @output_header_name@ unless
+ b4_defines_flag is set. This fixes two bugs reported by
+ Tim Van Holder in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
+ and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
+
+2003-01-21 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
+ we don't need to worry about yyerrlab1 being reported as an
+ "unused label" by non-GCC C compilers. The downside is that if
+ locations are used then a couple of statements are duplicated each
+ time YYERROR is invoked, but the upside is that the warnings
+ should vanish.
+ (yyerrlab1): Move code to YERROR.
+ (yyerrlab2): Remove. Change uses back to yyerrlab1.
+ This reverts some of the 2002-12-27 change.
+
+2003-01-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/output.c (symbol_printers_output): Fix typo that led
+ to core dump. Problem reported by Antonio Rus in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
