Just for speed, I assume. It's usually faster to keep a free list than to go back to the allocator each time. I don't know anything about the Ada compiler but I assume it needs to allocate a bunch of stmt_group structures. stmt_group_free_list is marked deletable which means that if a garbage collection occurs the memory taken up by the free list will be freed.
