Hi,

following up to a recent message to libstdc++@ I applied to mainline the

Tested x86_64-linux.

	* include/tr1_impl/array (_M_instance): Align naturally.
	* testsuite/ext/array_allocator/1.cc: Use ext/vstring,
	more solid than our current basic_string vs alignment.
	* testsuite/ext/array_allocator/2.cc: Likewise.
	* testsuite/ext/array_allocator/3.cc: Likewise.
