    OpenMP: Silence uninitialized variable warning in C++ front end.
    
    There's no actual problem with the code here, just a false-positive
    warning emitted by some older GCC versions.
    
    gcc/cp/ChangeLog
            * parser.cc (cp_finish_omp_declare_variant): Initialize
            append_args_last.
    
    (cherry picked from commit c978965b445079abbb88c22ba74de1e26e9f5b81)
