On vacpp `has_select_on_container_copy_construction` was incorrectly returning positive for a non-const `select_on_container_copy_construction`. This resulted in a compile error as it tried to call it for a const allocator. The workaround seemed to have just made things worse so I'm reverting it. It's actually not that bad a problem as a non-const `select_on_container_copy_construction` is probably a mistake. [SVN r74294]
