 *
 * \brief  This test checks that the BOOST_CURRENT_FUNCTION macro has semantics
 *         compatible with Boost.Log on the current platform.
 *
 * The point of this test is to determine whether the macro unfolds into a string literal
 * rather than a pointer to a string. This is critical because BOOST_LOG_WFUNCTION
 * relies on this fact - it determines the length of the literal by applying sizeof to it.
