    libstdc++: Fix narrowing conversions for 16-bit size_t [PR105681]

    On a 16-bit target such as msp430 we get errors about narrowing long
    values to size_t, which is only 16-bit. When --enable-libstdcxx-pch is
    used the <bits/extc++.h> header breaks the build because of these
    narrowing errors.
