Ah, I don't know what happens if invoked directly. What I meant is, if you
create a new empty project from within Visual Studio and include unit_test.hpp,
you get that error unless you set Linker->System->SubSystem to
"Console (/SUBSYSTEM:CONSOLE)" in the project options.

Yes, the error message is from the MSVC linker.
