Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
so that the tests still work even if POSIXLY_CORRECT is set.

for portability to K&R hosts. Fix typo: signed char is guaranteed
only to 127, not to 128.
* data/glr.c (yysigned_char): New type.
* data/yacc.c (yysigned_char): Likewise.
* tests/regression.at (Web2c Actions): signed char -> yysigned_char.
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.

default reduction.
Reported by Charles-Henry de Boysson.
* tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
check the length of the traces when %glr.
(_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
GLR's traces.
(AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
Test GLR parsers.
* data/glr.c (YYLEFTMOST_STATE): Fix its value.
(yyltype): Remove the yy prefix from the member names.
(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
next action to perform to match glr.c's decoding.
(yytable): Complete its comment.
<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.
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.
