    libstdc++: Disable over-zealous warnings about std::string copies
[PR103332]

    These warnings are triggered by perfectly valid code using std::string.
    They're particularly bad when --enable-fully-dynamic-string is used,
    because even std::string().begin() will give a warning.

    Use pragmas to stop the troublesome warnings for copies done by
    std::char_traits.
