    testsuite: The expect framework might introduce CR in output
    
    When running tests using the "sim" config, the command is launched in
    non-readonly mode and the text retrieved from the expect command will
    then replace all LF with CRLF. (The problem can be found in sim_load
    where it calls remote_spawn without an input file).
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/27_io/print/1.cc: Allow both LF and CRLF in test.
            * testsuite/27_io/print/3.cc: Likewise.
