// In the comparisons below, it is possible that T and U are signed and unsigned integer types, which generates warnings in some compilers.
// A cleaner fix would require common_type trait or some meta-programming, which would introduce a dependency on Boost.TypeTraits. To avoid
// the dependency we just disable the warnings.
