+ Support i18n of the parse error messages.
+ * TODO (lalr1.cc/I18n): Remove.

+
+ Port small part of master's 8901f32e so future ports are easier.
+ * data/lalr1.cc (yy::parser::yysyntax_error_): Always add second
+ argument, but name it in the function definition only when
+ verbose error messages are enabled and it'll thus be used.
+ (yy::parser::parse): Update use of yysyntax_error_.

+ portability: `<' and `>' are not always defined on addresses.
+ Specifically, don't sort objects by their memory addresses when
+ they're not allocated in the same array or other object. Though
+ I haven't found a test case where that fails on my platform, C
+ says the behavior is undefined.
+ * src/AnnotationList.c (AnnotationList__insertInto): Remove
+ FIXME. Use new id field of InadequacyList nodes rather than
+ their memory addresses when sorting.
+ (AnnotationList__compute_from_inadequacies): Add
+ inadequacy_list_node_count argument to pass to
+ InadequacyList__new_conflict.
+ * src/AnnotationList.h
+ (AnnotationList__compute_from_inadequacies): Update prototype
+ and documentation for new argument.
+ * src/InadequacyList.c (InadequacyList__new_conflict): Add
+ node_count argument and use it to assign a unique ID.
+ * src/InadequacyList.h (InadequacyListNodeCount): New typedef.
+ (InadequacyList): Add id field.
+ (InadequacyList__new_conflict): Update prototype and
+ documentation for new argument.
+ * src/ielr.c (ielr_compute_annotation_lists): Update
+ AnnotationList__compute_from_inadequacies invocation.

+
+ Fix handling of yychar manipulation in user semantic actions.
+ The problem was that yacc.c didn't always update the yychar
+ translation afterwards. However, other skeletons appear to be
+ fine. glr.c appears to already translate yychar before every
+ use. lalr1.cc does not define yychar and does not document its
+ replacement, yyla, for users. It does provide yyclearin, but
+ that does not manipulate yyla and thus requires no translation
+ update. In lalr1.java, yychar is out of scope during semantic
+ actions.
+ * NEWS (2.5): Document.
+ * data/yacc.c (YYBACKUP): Don't bother translating yychar into
+ yytoken here.
+ (yyparse, yypush_parse): Instead, translate before every use of
+ yytoken, and add comments explaining this approach.
+ * tests/actions.at (Destroying lookahead assigned by semantic
+ action): New test group checking that translation happens before
+ lookahead destructor calls at parser return. Previously,
+ incorrect destructors were called.
+ * tests/conflicts.at (%error-verbose and consistent
+ errors): New test group checking that translation happens at
+ syntax error detection before the associated verbose error
+ message and the associated lookahead destructor calls. While
+ the destructor call is fixed by this patch, the verbose error
+ message is currently incorrect due to another bug (see
+ comments in test group), so this is an expected failure for now.
