  Before writing out extra referenced types, the function
write_translation_unit does not check if this was an already emitted
declaration-only type.

This may actually be intentional, given the following comment.

  // We allow several *declarations* of the same class in the corpus,
  // but only one definition.

	* src/abg-writer.cc (write_translation_unit): Also check if an
	an extra referenced type is declaration-only and already
	emitted.
