+       * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
+       (Parser::parse): here.
+       Adjust: nerrs and errstatus is now replaced by...
+       (Parser::nerrs_, Parser::errstatus_): New.

+       * Makefile.am: Adjust.
+       * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
+       keeping local WGET and WGETFLAGS modifications from Paul Eggert.

+
+       When reducing initial empty rules, Bison parser read an initial
+       location that is not defined.  This results in garbage, and that
+       affects Bison's own parser.  Therefore we need (i) to extend Bison
+       to support a means to initialize this location, and (ii) to use
+       this CVS Bison to fix CVS Bison's parser.
+
+       * src/reader.h, reader.c (epilogue_augment): Remove, replace
+       with...
+       * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
+       * src/parse-gram.y: Adjust.
+       (%initial-action): New.
+       (%error-verbose): Since we require CVS Bison, there is no reason
+       not to use it.
+       * src/scan-gram.l: Adjust.
+       * src/Makefile.am (YACC): New, to make sure we use our own parser.
+       * data/yacc.c (yyparse): Use b4_initial_action.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+       * doc/bison.texinfo: Don't promote stdout for error messages.

+
+       * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

+
+       * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
+       Use them.

+
+       * data/lalr1.cc (Parser::reduce_print_): New.
+       Use it.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+       Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
+       error recovery loops.  This patch is based on
+       <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
+       Also, augment the similarity between lalr1.cc and yacc.c.
+       Note: the locations of error recovery rules are not correct yet.
+
+       * data/lalr1.cc: Comment changes to augment the similarity between
+       lalr1.cc and yacc.c.
+       (YYERROR): Goto to yyerrorlab, not yyerrlab1.
+       (yyerrlab1): Remove, but where it used to be (now the bottom part of
+       yyerrlab), when hitting EOF, pop the whole stack here instead of
+       merely falling thru the default error handling mechanism.
+       (yyerrorlab): New label, with the old contents of YYERROR,
+       plus the following change: pop the stack of rhs corresponding
+       to the production that invoked YYERROR.  That is how Yacc
+       behaves (required by POSIX).
+       * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
+       fail.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+       Tune local.at so that people can "autom4te -l autotest calc.at -o
+       calc" for instance, to extract a sub test suite.
+
+       * tests/testsuite.at: Move the initialization, Autotest version
+       requirement, and AT_TESTED invocation into...
+       * tests/local.at: here.
+       * tests/testsuite.at: Include it for compatibility with Autoconf
+       2.57.
+       * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
+       be ignore.
+
+2003-08-04  Paul Eggert  <eggert@twinsun.com>
+
+       Rework code slightly to avoid gcc -Wtraditional warnings.
+       * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
+       The returned value is now stored in *YY0.  All callers changed.
+       * src/output.c (merge_output): Adjust to the above change.
+
+2003-07-26  Paul Eggert  <eggert@twinsun.com>
+
+       * data/glr.c (YYASSERT): New macro.
+       (yyfillin, yydoAction, yyglrReduce, yysplitStack,
+       yyresolveStates, yyprocessOneStack):
+       Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
+       Derived from a suggestion by Frank Heckenbach.
+
 2003-07-25  Paul Eggert  <eggert@twinsun.com>
 
+       * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
+       for portability to K&R C (after ansi2knr, presumably).  See
+       <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
+       by Frank Heckenbach, though I have omitted the structure-initialization
+       part of his glr-knr.diff patch since I recall that the Portable
+       C Compiler didn't require that change.

        Let the user specify how to allocate and free memory.
