1. Use 0U
2. Define ULONG uzero = 0; and use it in comparisons.
3. Define your own macros which take 2 args, cast to right type one of them and
forward them to BOOST_CHECK_EQUAL.

How can I know which one is constant? What is the correct type out of 2? Type of
left argument or right? I thought about automatic type promotion at some point,
but never came up with reasonable design.
