+
+ Use b4_type_names for the union type.
+ The union used to compute the size of the variant used to iterate over the
+ type of all the symbols, with a lot of redundancy. Now iterate over the
+ lists of symbols having the same type-name.
+
+ * data/lalr1.cc (b4_char_sizeof_): New.
+ (b4_char_sizeof): Use it.
+ Adjust to be called with a list of numbers instead of a single
+ number.
+ Adjust its caller for new-line issues.

+
+ Define the "identifier" of a symbol.
+ Symbols may have several string representations, for instance if they
+ have an alias. What I call its "id" is a string that can be used as
+ an identifier. May not exist.
+
+ Currently the symbols which have the "tag_is_id" flag set are those that
+ don't have an alias. Look harder for the id.
+
+ * src/output.c (is_identifier): Move to...
+ * src/symtab.c (is_identifier): here.
+ * src/symtab.h, src/symtab.c (symbol_id_get): New.
+ * src/output.c (symbol_definitions_output): Use it to define "id"
+ and "has_id".
+ Remove the definition of "tag_is_id".
+ * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
+ "tag_is_id" were used to produce code.
+ We still use "tag" for documentation.
