gcc gives me:

   invalid cast from type ‘uint32_t’ to type ‘boost::endian::ubig32_t

I've only ever used reinterpret_cast on pointers, so doing the above
didn't even occur to me. I had to try it to see whether or not it would
work. Using static_cast doesn't work because it does the byteswap
operation twice, making the function a no-op.
