    libstdc++: xfail io_context/pipe users on rtems
    
    A handful of tests fail on rtems because pipe() always returns -1, and
    the io_context ctor throws a system error when pipe() fails.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/experimental/net/timer/waitable/cons.cc: xfail on
            RTEMS.
            * testsuite/experimental/net/timer/waitable/dest.cc: Likewise.
            * testsuite/experimental/net/timer/waitable/ops.cc: Likewise.
            * testsuite/experimental/net/internet/resolver/ops/lookup.cc:
            Likewise.
            * testsuite/experimental/net/internet/resolver/ops/reverse.cc:
            Likewise.
    
    TN: V617-003
