* data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
b4_cc_constructor_calls, b4_cc_constructor_call,
b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
definitions.
(yy::b4_parser_class_name::b4_parser_class_name): Take extra
parse-param arguments.
(yy::b4_parser_class_name): Declare instance variables to
hold parse-param arguments.
* tests/calc.at: s/value/semantic_value/ because value clashes
with a member of yy::b4_parser_class_name. Adjust C++ code
to handle %parse-param. Enable %parse-param test in C++.
Declare to be of type suitable for the ninf value itself, not of
type suitable for the corresponding table, since the latter might
be unsigned but the ninf value might be negative. This fixes a
bug reported by Alexandre Duret-Lutz in
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
before initial_columns.
(location.hh): Use consistent variable names when defining the
operator<<.
Use "last" so that we subtract from Positions, not from unsigned.
(CXX): this, to keep the original Autoconf semantics.
Require 2.57.
* data/lalr1.cc: Fix b4_copyright invocations.
If YYDEBUG is not defined, don't depend upon name_ being defined.
(location.hh): Include string and iostream.
(Position::filename): New member.
(Position::Position ()): New.
(operator<< (Position)): New.
(operator- (Position, int)): New.
(Location::first, Location::last): Rename as...
(Location::begin, Location::end): these, to mock the conventional
iterator names.
(operator<< (Location)): New.
* tests/atlocal.in (CXX): New.
* tests/testsuite.at (AT_COMPILE_CXX): New.
* tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
locations in a more synthetic way.
(AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
lalr1.cc is used.
Adjust the C locations to match those from Emacs: first column is
column 0.
Change all the expected results.
Conform to the GCS: simplify the locations when applicable.
(LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
(LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
these CPP macros with the m4 macros new defined by...
(AT_CHECK_PUSHDEFS): this, i.e.:
(AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
(AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALSm AT_LEX_PRE_ARGS)
New macros.
(AT_CHECK_POPDEFS): Undefine them.
(AT_CHECK_CALC_LALR1_CC): New.
Use it for the first lalr1.cc test.

* data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
when the stacks contain one element, as the loop would otherwise
free the last state, and then use the top state (the one we just
popped). This means that the initial elements will not be freed
explicitly, as is the case in yacc.c; it is not a problem, as
these elements have fake values.
since this causes problems when __file__ contains character
sequences like "@" that are treated specially by src/scan-skel.l.
Instead, just use the file's basename. This fixes the bug
reported by Martin Mokrejs in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
Add support for --trace=skeleton.
* src/scan-skel.l: %option debug.
Scan strings of non-@ or n instead of character by character.
(scan_skel): Handle trace_skeleton.
(QPUTS): New.
(@output_parser_name@, @output_header_name@): ``Restore'' their
support (used to be M4 macros).
* data/yacc.c: Quote larger chunks, a la glr.c.
* data/lalr1.cc: Likewise.
The header guards are no longer available, so use some other
string than `YYLSP_NEEDED'.
(b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
b4_output_header_suffix, b4_output_header_name, b4_header_guard):
Remove, since they couldn't handle arbitrary characters in file
names.
Use YYSLP_NEEDED instead of b4_header_guard.
* 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.
expected token.
* tests/actions.at (Printers and Destructors): Adjust.
* tests/calc.at (Calculator $1): Adjust.
* data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
error message, do not report the parser accepts the error token in
that state.
(save_column): sp, sp1, and sp2 are state_number_t.
(prepare): Rename `final' as `final_state_number', `nnts' as
`nterms_number', `nrules' as `rules_number', `nstates' as
`states_number', and `ntokens' as `tokens_number'. Remove `nsym',
unused.
* data/yacc.c, data/glr.c, data/lalr1.cc: Adjust.
* data/lalr1.cc (nsym_): Remove, unused.
