That's one nice benefit from using enums.
* data/skeletons/lalr1.java (YYSYMBOL_YYEMPTY): No longer define it.
Use 'null' instead.
* examples/java/calc/Calc.y, tests/local.at: Adjust.
* data/skeletons/bison.m4, data/skeletons/c++.m4, data/skeletons/c.m4,
* data/skeletons/glr.cc, data/skeletons/lalr1.cc,
* data/skeletons/lalr1.d, data/skeletons/lalr1.java:
Refer to the "kind" of a symbol, not its "type", where appropriate.
* doc/bison.texi: Replace occurrences of "token type" with "token
kind".
Stop referring to the "macro definitions" of the token kinds, just
name them "definitions".

examples: reccalc: really compile cleanly in C99
news: announce that Bison 3.6 drops YYERROR_VERBOSE
news: update for 3.5.4
style: fix spellos
typo: succesful -> successful
package: improve the readme
java: check and fix support for api.token.raw
java: style: prefer 'int[] foo' to 'int foo[]'
build: fix syntax-check issues
tests: recheck: work properly when the test suite was interrupted
doc: c++: promote api.token.raw
build: fix compatibility with old compilers
examples: reccalc: compile cleanly in C99
The previous fix does not suffice, and actually managed to make things
worse by defining yyscan_t twice in parse.y...
Reported by kencu.
https://trac.macports.org/ticket/59927#comment:29
* examples/c/reccalc/parse.y (yyscan_t): Define it with the same
guards as used by Flex.
The first name is too long. We already have `yypstate`, so
`yypcontext` is ok. We are also migrating to using `*_t` for our
types.
* NEWS, data/skeletons/glr.c, data/skeletons/yacc.c, doc/bison.texi,
* examples/c/bistromathic/parse.y, src/parse-gram.y, tests/local.at:
(yyparse_context_t, yyparse_context_location, yyparse_context_token):
Rename as...
(yypcontext_t, yypcontext_location, yypcontext_token): these.
The Java enums are very different from the C model. As a consequence,
one cannot "build" an enum directly from an integer, we must retrieve
it. That's the purpose of the SymbolType.get class method.
* data/skeletons/java.m4 (b4_symbol_enum, b4_case_code_symbol)
(b4_declare_symbol_enum): New.
* data/skeletons/lalr1.java: Use SymbolType,
SymbolType.YYSYMBOL_YYEMPTY, etc.
* examples/java/calc/Calc.y, tests/local.at: Adjust.
* tests/local.at (AT_LANG_MATCH, AT_YYERROR_DECLARE(java))
(AT_YYERROR_DECLARE_EXTERN(java), AT_PARSER_CLASS): New.
(AT_MAIN_DEFINE(java)): Use AT_PARSER_CLASS.
* tests/scanner.at: Add a test for Java.
* data/skeletons/lalr1.java (yytranslate_): Cast the result.
* data/skeletons/d.m4 (b4_symbol_enum, b4_declare_symbol_enum): New.
* data/skeletons/lalr1.d: Use them.
Use SymbolType, SymbolType.YYSYMBOL_YYEMPTY etc. where appropriate.
(undef_token_, token_number_type, yy_error_token_): Remove.
* tests/local.mk (recheck): Look at the per-test logs, not the overall
log, which, when interrupted, contains only information about... the
tests that passed.

See https://lists.gnu.org/r/bug-bison/2020-03/msg00021.html
and https://trac.macports.org/ticket/59927.
* src/system.h (GCC_VERSION): New.
Use it to control IGNORE_TYPE_LIMITS_BEGIN and
IGNORE_TYPE_LIMITS_END.
Because of the insane current implementation of glr.cc, things are a
bit nasty. We will rename symbol_number_type as symbol_type_type
later, to keep this commit small.
* data/skeletons/c++.m4 (b4_declare_symbol_enum): New.
Also define YYNTOKENS to avoid type clashes when yyntokens_ was
actually defined in another enum.
Use it.
(symbol_number_type): Be an alias of symbol_type_type.
Use YYSYMBOL_YYEMPTY and the like.
Use symbol_number_type where appropriate.
(empty_symbol): Remove.
(yytranslate_): Use symbol_number_type, not token_number_type.
* data/skeletons/lalr1.cc: Use symbol_number_type where appropriate.
Adjust to the replacement of empty_symbol by YYSYMBOL_YYEMPTY.
(yy_error_token_, yy_undef_token_, yyeof_, yyntokens_): Remove.
Adjust dependencies.
* data/skeletons/glr.cc: Use symbol_number_type where appropriate.
Forward definitions of YYSYMBOL_YYEMPTY, etc. to glr.c.
* tests/headers.at: Accept YYNTOKENS and other YYSYMBOL_*.
* tests/local.at (AT_YYERROR_DEFINE(c++)): Use symbol_number_type.
