================
Comment at: src/experimental/filesystem/operations.cpp:27
+// We can use the presence of UTIME_OMIT to detect platforms that do not
+// provide utimensat, with some exceptions on OS X.
+#if !defined(UTIME_OMIT) ||                                                    \
----------------
Would it be easier to read if we split this test into two halves - one for Apple platforms and the other for the rest of the world?

    #if !defined(__APPLE__)
    # if !defined(UTIME_OMIT)
    # define _LIBCPP_HAS_NO_UTIMENSAT
    # endif
    #else
    .....
    #endif
