Ah.

Well, in addition to God, you might ask me. :-) By default they go nowhere. But 
they can be redirected, by the ordinary redirection operators.

"If the compiler is MSVC, allocate a console window". Hm. You better inform 
those folks that they're doing meaningless things.

That's my preference. An ordinary GUI subsystem app, with a standard `main`. Why 
write more to get non-standard code? That's just silly. It's like writing `void 
main`, one character more, just to get a non-standard idiot's[1] version.

There's no mess wrt. this in the Windows architecture.

To wit, the MinGW g++ compiler / toolchain does not have this problem.

Technical: `main` and `wMain` and `winMain` and `wWinMain` are not supported at 
the Windows API level (disregarding the MSVC runtime as part of the API).


Cheers & hth.,

Notes:
[1] When I'm writing "idiot's" that's just an exaggeration to put it to a point. 
For example, Bjarne used that `void main` at least once in the second edition of 
The C++ Programming Language, and I'm not calling him an idiot. :-)
