In C++03, a bunch of the arithmetic/logical/comparison functors (such as negate/bit_not.pass/logical_not) were defined as deriving from unary_funtion. That restriction was removed in C++11, but the tests still check for this. Change the test to look for the embedded types first_argument/second_argument/result_type. No change to the library, just more standards-compliant tests. Thanks to STL @ Microsoft for the suggestion.
