Fix a bug where ::warning() was called with a va_list argument instead of an actual vararg list. Also cleaned up the format for warnings. (Previously some would start with "warning - warning - Warning:" which was a bit redundant)

module scope4;
int main()
{
    int i;
    try
    {
        return i;
    }
    finally
    {
        //i = 1;
    }
}
