    libstdc++: Adjust Filesystem TS test for Windows
    
    The Filesystem TS isn't really supported for Windows, but the FAIL for
    this test is just because it doesn't match what happens on Windows.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/experimental/filesystem/operations/create_directories.cc:
            Adjust expected results for Windows.
    
    (cherry picked from commit 61b783995fac5355827ada1f8544052119a23606)
