+
+ * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions

+
+ 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.

+ 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>

+
+ * 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.

+
+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.
+ Derived from a suggestion by Frank Heckenbach in
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
+ * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
+ All uses of free, malloc, realloc changed to use these macros,
+ and unnecessary casts removed.
+ * data/yacc.c (YYFREE, YYMALLOC): Likewise.
+
+2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
+
+ * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

+ (trivial change)

+ Problem reported by Frank Heckenbach in
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
+
+ Port to Forte Developer 7 C compiler.
+ * data/glr.c (struct YYLTYPE): If locations are not being used,
+ declare a single dummy member, as empty structs do not conform
+ to the C standard.
+ (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
+ the Forte Developer 7 C compiler complains that end-of-loop
+ code is not reached.
+
+2003-06-17 Paul Eggert <eggert@twinsun.com>
+
+ * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
