    libstdc++: Do not use dirent::d_type unconditionally
    
    These new tests should not use the d_type member unless it's actually
    present on the OS.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/27_io/filesystem/iterators/error_reporting.cc: Use
            autoconf macro to check whether d_type is present.
            * testsuite/experimental/filesystem/iterators/error_reporting.cc:
            Likewise.
