    How does this compile on your machine?

    I just need the following compiler output for this, plus the compiler you're running, if you don't mind.

    Code:
     int main() {
     _10;
     }
    Thanks.
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }

    Should it have done something?

    Variables and functions that start with _ are supposed
    to reserved for the compiler. It's possible it could do something.

    >> Should it have done something?

    Nope. Well, it should compile with errors, of course...I'm trying to use the compiler errors to display info to the programmer, simplified, something like:

    int main(){
    RANGE(WHITE_BRUSH);
    }

    ...would give me the total of stock brushes available to a windows application by passing just a single known value. Sounds like macro hell, huh? Anyway, I just wanted to know if the number shows in the error gutter on any given compiler...
