Boost C++ Libraries: Ticket #12459: Support polymorphic_allocator in boost::unordered_map/set

For now, you might be able to get it work by defining BOOST_UNORDERED_USE_ALLOCATOR_TRAITS to 1. That will tell it to use std::allocator_traits.

Thanks for pointing, it solved the issue. However I think it would be much better if this was either documented or enabled by default for compilers supporting it.

The "for now" was to suggest that this is a temporary workaround. I can't do anything at the moment because we're at the end of a release cycle.

The same problem with boost::multi_index class. It expects Allocator::rebind struct.
