        * system.h: Conditionally include "unique-ptr.h" if
        INCLUDE_UNIQUE_PTR is defined.
        * unique-ptr-tests.cc: Remove include of "unique-ptr.h" in favor
        of defining INCLUDE_UNIQUE_PTR before including "system.h".

include/ChangeLog:
        * unique-ptr.h: Make include of <memory> conditional on C++11 or
        later.
