You can figure out that a signed value is a bad idea without having to guess
about compiler implementations.

If you ever try to shift a signed value to the right, and the top bit is set,
the top bit will stay set, and any bits to the left of the new location of what
once was the top bit will also be set.

This is something you obviously don't want if you are ever going to shift one of
these things to the right.
