C++17 deprecated, and C++20 fully removed, the std::allocator<T>::const_pointer typedef (https://en.cppreference.com/w/cpp/memory/allocator). So gcc10 fails to compile this file. The selected fix was to completely remove the hint argument because (a) it was ignored anyway, and (b) std::allocator's allocate() function also chose to remove its hint argument in C++20 (https://en.cppreference.com/w/cpp/memory/allocator/allocate).
