Declaration of allocator_arg should be constexpr to ensure constant initialization.

[ Batavia (2009-05): ]

We agree with the proposed resolution. Move to Tentatively Ready.

Proposed resolution:

Change 20.2 [memory] p2:

// 20.8.1, allocator argument tag
struct allocator_arg_t { };
constexpr allocator_arg_t allocator_arg = allocator_arg_t();
