[Boost-users] iterator_adapter/iterator_tag/std::distance bug

I used boost::iterator_adapter with a std::vector iterator, all parameters set 
to boost::use_default. (So this is the same as a plain std::vector iterator)
With this configuration, the iterator tag is recognized as "input_iterator_tag" 
not "random_iterator_tag" as it must be. This hurts because the iterator tag is 
used to select the right std::distance function.
I could solve the problem by explicitly setting the traversal type template 
parameter to "std::random_access_iterator_tag", 
while "boost::random_access_traversal_tag" also didn't work. The compiler is 
VC8.
