The possible base classes of std::allocator are new_allocator and malloc_allocator, which both cause a non-reserved name to be declared in every program that includes the definition of std::allocator. This is non-conforming. This change replaces __gnu_cxx::new_allocator with std::__new_allocator which is identical except for using a reserved name. The non-standard extension __gnu_cxx::new_allocator is preserved as a thin wrapper over std::__new_allocator. There is no problem with the extension using a non-reserved name now that it's not included by default in other headers. The same change could be done to __gnu_cxx::malloc_allocator but as it's not the default configuration it can wait. libstdc++-v3/ChangeLog: PR libstdc++/64135 * config/allocator/new_allocator_base.h: Include <bits/new_allocator.h> instead of <ext/new_allocator.h>.
