437c2d8000 Restore --no-lines. 
Reported by Jim Kent.
* data/c.m4 (b4_syncline): New.
* data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
* src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
* src/output.c (user_actions_output): Likewise.
(prepare): Define 'b4_synclines_flag'.

f1886bb280 * data/yacc.c (m4_int_type): New. 
* data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
char' as only yacc.c wants K&R portability.
* data/glr.c (yysigned_char): Remove.
* data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
Reported by Quoc Peyrot.

f50adbbdb0 GLR parsers sometimes raise parse errors instead of performing the 
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.

c0ad8bf3c2 * data/yacc.c: Guard the declaration of yytoknum also with 
`#ifdef YYPRINT', so it is declared only when used.

5719c1092f and Akim Demaille <akim@epita.fr> 
* data/bison.simple.new (yyerrlab1): Be sure to pop and destroy
what's left on the stack when the error recovery hits EOF.

short.

d803322e27 * tests/calc.at, tests/output.at, tests/regression.at, 
* tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
now the tests are run in private dirs, therefore AC_CLEANUP and
family can be simplified to 0-ary.
* tests/atlocal.in: Now that we run `elsewhere' than in tests/,
use abs. path to find config.h.
* tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
stderr, there can be way too much random noise.
Instead pass -Werror to GCC and rely on the exit status.
