Need help compiling a minor change

Ah cool, that would be cool if you can compile it, in the CIrrDeviceWin32.cpp it says to add the following line to the case WM_SYSCOMMAND: I can email the cpp file if you prefer but it was easy for me to find. What is the MingW dll is it possible for me to look and compile after looking into it or is it a purchased component?

I hope this will do what i want for now anyway, thanks
...
case WM_SYSCOMMAND:
    // prevent screensaver or monitor powersave mode from starting
    if ((wParam & 0xFFF0) == SC_SCREENSAVE ||
        (wParam & 0xFFF0) == SC_MONITORPOWER)
       
    {
    return 0;
    }
    else if ((wParam & 0xFFF0) == SC_KEYMENU) // added
    {
    return 0;
    }
   
    break;
