9860,mem_fun_cxx98 doesn't compile with c++11,chris.cooper@…,Douglas Gregor,"Using clang++ from XCode 5.1 on OSX 10.9.2, mem_fun_cxx98 won't compile, it gives this error:

mem_fun_cxx98.cpp:34:46: error: invalid operands to binary expression ('std::__1::basic_ostream<char>' and 'ostream' (aka 'basic_ostream<char>'))
    BOOST_TEST(f2(&x, boost::ref(std::cout)) == std::cout);
../../../boost/detail/lightweight_test.hpp:186:28: note: expanded from macro 'BOOST_TEST'
#define BOOST_TEST(expr) ((expr)? (void)0: ::boost::detail::test_failed_impl(#expr, __FILE__, __LINE__, BOOST_CURRENT_FUNCTION))
1 error generated.

Peter Dimov suggested the following fix:

It should probably say

    BOOST_TEST( &f2(&x, boost::ref(std::cout)) == &std::cout );

You can say std::cout == std::cout in pre-C++11, but it doesn't do anything
sensible. This no longer compiles in C++11.
