+       Provide convenience constructors for locations and positions.
+       * data/location.cc (position::position): Accept file, line and
+       column as arguments with default values.
+       Always qualify initial line and column literals as unsigned.
+       (location::location): Provide convenience constructors.

+
+       Instead of using make_symbol<TOK_FOO>, generate make_FOO for each token type.
+       Using template buys us nothing, and makes it uselessly complex to
+       construct a symbol.  Besides, it could not be generalized to other
+       languages, while make_FOO would work in C/Java etc.
+       
+       * data/lalr1.cc (b4_symbol_): New.
+       (b4_symbol): Use it.
+       (b4_symbol_constructor_declaration_)
+       (b4_symbol_constructor_definition_): Instead of generating
+       specializations of an overloaded template function, just generate
+       several functions whose names are forged from the token names
+       without the token.prefix.
+       (b4_symbol_constructor_declarations): Generate them for all the
+       symbols, not just by class of symbol type, now that instead of
+       specializing a function template by the token, we generate a
+       function named after the token.
+       (b4_symbol_constructor_specialization_)
+       (b4_symbol_constructor_specializations): Remove.
+       * etc/bench.pl.in: Adjust to this new API.

+
+       %define token.prefix.
+       Provide a means to add a prefix to the name of the tokens as output in the
+       generated files.  Because of name clashes, it is good to have such a
+       prefix such as TOK_ that protects from names such as EOF, FILE etc.
+       But it clutters the grammar itself.
+       
+       * data/bison.m4 (token.prefix): Empty by default.
+       * data/c.m4 (b4_token_enum, b4_token_define): Use it.
+       * data/lalr1.cc (b4_symbol): Ditto.

        Compute at M4 time some of the subtractions.
