Could you declare (not define) `constructible_with_allocator_suffix` and `constructible_with_allocator_prefix` in a separate header so that they can be specialised without including all the other things? It might be useful to include a definition of `allocator_arg_t` in case it needs to write a constructor using it.",Bugs,closed,To Be Determined,container,Boost 1.50.0,Problem,fixed,,
