i've got to do a bit of pure ANSI C and i'm trying to do it in Visual Studio 2010. Problem is; regardless of setting the compiler to pure C and flipping the \Za compiler switch to disable windows extensions - the code just won't compile:

#define _USE_MATH_DEFINES
#include <iostream>
#include <math.h>

using namespace std;

int main()
{
    cout << M_PI;
    return 0;
}

This is in a file called Test.c - there are no precompiled headers and everything should be fine, but this is what the compiler spits out:

I'm not that experienced with VS and C, but i've looked around and nothing I do seems to work. I'm guessing it'll be something silly. Thanks in advance

(Note: this same error occurs with absolutely no references to any math libraries)
