+
+ Let nondeterministic skeletons be usable with deterministic
+ tables.
+
+ With the patch, GAWK compiled by GCC without -O2 passes its test
+ suite using a GLR parser driven by LALR tables. It fails with -O2
+ because `struct stat' gives two different answers on my machine:
+ 88 (definition of an auto var) and later 96 (memset on this var).
+ Hence the stack is badly corrumpted. The headers inclusion is to
+ blame: if I move the awk.h inclusion before GLR's system header
+ inclusion, the two struct stat have the same size.
+
+ * src/tables.c (pack_table): Always create conflict_table.
+ (token_actions): Always create conflict_list.
+ * data/glr.c (YYFLAG): Remove, unused.

+ (yytable): Complete its comment.
+ (yygetLRActions): Map error action number from YYTABLE from
+ YYTABLE_NINF to 0.
+ (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
+ (which was a bug: it should have been YYTABEL_NINF, and yet it was
+ not satisfying as we could compare an YYACTION computed from
+ YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
+ only value for error actions.
+ (yyreportParseError): In verbose parse error messages, don't issue
+ `error' in the list of expected tokens.
+ * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the

+ Fix problem reported by Henrik Grubbstroem in
+ <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
+ "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
+ because the Bison parser reads the second action before reducing
+ the first one.
+ * src/scan-gram.l (rule_length): New static var.
+ Use it to keep track of the rule length in the scanner, since
+ we can't expect the parser to be in lock-step sync with the scanner.
+ (handle_action_dollar, handle_action_at): Use this var.
+ * tests/actions.at (Exotic Dollars): Test for the problem.
