Hi Andrey

On VS2008, this code ...

#include <boost/log/trivial.hpp>
#include <ostream>

int main()
{
    BOOST_LOG_TRIVIAL(trace) << "This is a" << std::endl << "multiline 
message";
    return 0;
}

... fails compilation with the following error:

error C2679: binary '<<' : no operator found which takes a right-hand 
operand of type 'overloaded-function' (or there is no acceptable conversion)

Now I do realize that "\r\n" would be a better choice here, as the flushing 
that comes with std::endl is not necessary. However, some developers in our 
team seem to prefer std::endl nevertheless. So, the question is: Is this 
intentional or just an oversight?

BTW, only std::endl, std::ends and std::flush don't work, all the other 
manipulators do.

Thanks,
