it against YYEMPTY and so forth), work on yytoken (i.e., set
it to YYEMPTY etc.).
(yydestruct): Replace with a b4_yydestruct_generate invocation.
(b4_symbol_actions): Remove.
* data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
for 0, end-of-input.
Restore.

yylex.

b4_user_formals and b4_user_args.
(yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
(yyreportAmbiguity): When using a pure parser, also need
the location, and the parse-params.
Adjust callers.
(yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
When using a pure parser, also need the parse-params.
Adjust callers.
* tests/calc.at: Test pure (%pure-parser) and absolutely pure
(%pure-parser + %parse-param) LALR and GLR parsers.
(AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
(_AT_DATA_CALC_Y): Equip for purity of yyerror.

(Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
(Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
(Error Reporting): Adjust to these new directives.
Document %error-verbose, deprecate YYERROR_VERBOSE.
* 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.
arguments and output `void'.

(b4_c_function_decl, b4_c_ansi_function_def)
(b4_c_ansi_function_decl): New.
Change the interpretation of the arguments: before `int, foo', now
`int foo, foo'.
* data/yacc.c (yyparse): Prototype and define thanks to these.
Adjust b4_c_function_def uses.
* data/glr.c (yyparse): Likewise, but ANSI only.
* src/parse-gram.y: Add the definition of the %lex-param and
%parse-param tokens, plus their rules.
Drop the `_' version of %glr-parser.
Add the "," token.
