If you have things like:

+      template<typename _UniformRandomNumberGenerator,
+	       typename _ForwardIterator>
+	void
+	__generate(_ForwardIterator __f, _ForwardIterator __t,
+		   _UniformRandomNumberGenerator& __urng)


then probably you want to swap the template parameters (or viceversa):

+      template<typename _ForwardIterator,
+	       typename _UniformRandomNumberGenerator>
+	void
+	__generate(_ForwardIterator __f, _ForwardIterator __t,
+		   _UniformRandomNumberGenerator& __urng)


Frankly, I'm finding the forwarding via __gnu_cxx::__normal_iterator 
pretty ugly. Can't we have instead an internal, private, 
__generate_impl(_ForwardIterator, _ForwardIterator, 
_UniformRandomNumberGenerator&, const param_type&) which is called by 
both the variant of __generate taking iterators and the variant taking 
pointers?
