    libstdc++: Do not use fast_float for 16-bit size_t [PR104870]

    The preprocessor condition for using fast_float should match the one in
    the header, and require at least 32-bit size_t.

            * src/c++17/floating_from_chars.cc: Check __SIZE_WIDTH__ >= 32
            before using fast_float.
