Avoid undefined compiler behavior

Technically, shifting a signed value beyond its maximum range is
undefined behavior in C++.  A bare integer literal is signed, and
defaults to 'int'.  On platforms where 'int' is 32-bits, we
shift outside this range with 1 << 31.

We make our literal an unsigned integer to avoid this.
