our code base uses boost 1.54 with GCC 4.4.7 on CentOS 6, compiling as C++98.
we're interested in using an allocator with state with the standard containers, so are investigating the boost container library in boost 1.54, in particular, instantiating these containers with a boost::container::scoped_allocator_adaptor<MyArena> style argument.
1) i notice that boost::unordered_xxx<> is not part of the boost container library. does this mean that these classes are not aware of the C++11 allocator model? a casual inspection of the code suggests that this might be the case
