* @brief An allocator that uses global `new`, as per C++03 [20.4.1].
* @ingroup allocators
*
* This is precisely the allocator defined in the C++ Standard.
* - all allocation calls `operator new`
* - all deallocation calls `operator delete`
*
* This is a non-standard extension that can be used to guarantee
* allocation from `new` even if the library has been configured to
* use a different implementation for `std::allocator`.
*
* @tparam _Tp Type of allocated object.
*
* @headerfile ext/new_allocator.h
