+ When reducing initial empty rules, Bison parser read an initial

+
+ Fix a GLR parser bug I reported in February; see
+ <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
+ The problem was that GLR parsers did not conform to the C standard,
+ because actions like { $1 = $2 + $3; } expanded to expressions
+ that invoked YYFILL in separate subexpressions, and YYFILL assigned
+ to a local variable. The C standard says that expressions
+ like (var = f ()) + (var = f ()) have undefined behavior.
+ Another problem was that GCC sometimes issues warnings that
+ yyfill and its parameters are unused.
+
+ * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
+ as possibly unused.
+ (yyfill): New function.
+ (YYFILL): Use it.
+ (yyuserAction): Change type of yynormal to bool, so that it matches
+ the new yyfill signature. Mark it as possibly unused.
+
+
+ Follow up on a bug I reported in February, where a Bison-generated
+ parser can loop. Provide a test case and a fix for yacc.c. I
+ don't have a fix for lalr1.cc or for glr.c, unfortunately.
+ The original bug report is in:
+ <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
+
+ * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
+ macro's size was becoming unwieldy.
+ (yyerrlab): Do not discard an empty lookahead symbol, as this
+ might destroy garbage.
+ (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, and POSIX requires this behavior.
+ (yyerrlab1): Use YYPOPSTACK instead of its definiens.
+ * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
+ Define 'alarm' to do nothing if unistd.h is not available.
+ Add a new rule "exp: '-' error;" to test the above change to
+ data/yacc.c. Use 'alarm' to abort any test taking longer than
+ 10 seconds, as it's probably looping.
+ (AT_CHECK_CALC): Test recovery from error in new grammar rule.
+ Also, the new yacc.c generates two fewer diagnostics for an
+ existing test.
