 Fine it looks cleaner and compiles... thanks Stephen.

 BTW 
 I think might be possible improve functional/performance parts too. It's the 
 list handling I'm thinking of.

 I've observed that in most cases there is only one leaf_info in the leaf list.
 In 96% of current Internet prefixes in the router I just looked into (below). 
 So optimizing for this case could be an idea. Some variant were the leaf holds
 the leaf_info data direct could be worth testing.

 Cheers.
