It  looks to me like the "if (0)" is preventing those new locals from
being written to the output file:

> +  // Next do all the symbols which have been generated as local.
> +  // They too must appear before all global symbols.
> +  if (0)
> +  for (Forced_locals::const_iterator p = this->generated_locals_.begin();
> +       p != this->generated_locals_.end();
> +       ++p)
> +    {

Did you forget to remove a hack?
