    libstdc++: Fix test that fails for C++98 mode
    
    When I backported r11-2760 as r10-8644 I simplified it and didn't add
    the new _GLIBCXX11_DEPRECATED macro. That means that the macro used on
    the old iostream members does nothing for C++98 mode, and so the test
    fails. This adjusts the test to only expect warnigns for C++11 and
    later.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/27_io/types/1.cc: Add c++11 target selector to
            warnings.
