The failing tests are using glr.cc only, which I don't understand, the
problem is rather in glr.c, so I would expect glr.c tests to also fail.

To write unit tests for their scanners, some users depended on
symbol_type::token():
Lexer lex("12345");
symbol_type t = lex.nextToken();
assert(t.token() == token::INTLIT);
assert(t.value.as<int>() == 12345);
But symbol_type::token() was removed in Bison 3.5 because it relied on
a conversion table. So users had to find other patterns, such as
assert(t.type_get() == by_type(token::INTLIT).type_get());
which relies on several private implementation details.
As part of transitioning from "token type" to "token kind", and making
this a public and documented interface, "by_type" was renamed
"by_kind" and "type_get()" was renamed as "kind()". The latter had
backward compatibility mechanisms, not the former.
In Bison 3.6 none of this should be used, but rather
assert(t.kind() == symbol_kind::S_INTLIT);

* data/skeletons/c++.m4 (by_type): Make it an alias to by_kind.
I don't plan to fix everything in one go. But this was in the way of
the next commit.
* data/skeletons/lalr1.java: Avoid space before parens.
* tests/java.at: Adjust.
