I'm sorry if I missed the explanation for it... what is the use case of this feature?
The motivating use case is the Microsoft Visual Studio IDE, which treats cout and cerr as two separate streams. So you get all the cout output followed by all the cerr output, when what you really want is the equivalent of command line 2>&1 Just changing the lightweight_test.hpp output to std::cout isn't a good solution because (1) std::cerr is really the right stream for most uses, and (2) a change might break existing scripts that assume std::cerr. Detecting VC++ isn't a good solution because (1) there doesn't seem to be any way to distinguish between compiling under the IDE versus the command line, and (2) there may be other IDE or test frameworks that have the same problem. Thus the macro. I'll add this comment: // IDE's like Visual Studio perform better if output goes to std::cout or // some other stream, so allow user to configure output stream:

You should add your name to the copyright.
