frage zwecks hex-files

hi leute. kenn mich irgenwie nicht so recht aus mit der erstellung von 
hex-files. wollte einfach mal zum ausprobieren dieses c-programm mit 
mfile von winavr in ein  makefile und dann mit programmers-notepad in 
ein hex-file umwandeln.könnt ihr mir bitte genau erklären wie ich dabei 
vorgehe?
kann es sein dass winavr die includes gar nicht kennt? was muss ich dann 
machen?hier der quelltext:

#include <iostream>
#include <stdlib.h>
#include <time.h>

using namespace std;

void Start ();
void GetResults ();

int  i, j, life, maxrand;
char c;


void
Start ()
{
     i = 0;
     j = 0;
     life = 0;
     maxrand = 6;

     cout << "Select difficulty mode:\n"; // the user has to select a 
difficutly level
     cout << "1 : Easy (0-15)\n";
     cout << "2 : Medium (0-30)\n";
     cout << "3 : Difficult (0-50)\n";
     cout << "or type another key to quit\n";
     c = 30;

     cin >> c;                   // read the user's choice
     cout << "\n";

     switch (c)
     {
        case '1' : maxrand = 15;  // the random number will be between 0 
and maxrand
        break;
        case '2' : maxrand = 30;
        break;
        case '3' : maxrand = 50;
        break;
        default : exit(0);
        break;
     }

     life = 5;         // number of lifes of the player
     srand( (unsigned)time( NULL ) ); // init Rand() function
     j = rand() % maxrand;  // j get a random value between 0 and 
maxrand

     GetResults();

}


void
GetResults ()
{
     if (life <= 0)
        // if player has no more life then he lose
     {
        cout << "You lose !\n\n";
        Start();
     }

     cout << "Type a number: \n";
     cin >> i;          // read user's number

     if ((i>maxrand) || (i<0)) // if the user number isn't correct, 
restart
     {

        GetResults();
     }

     if (i == j)
     {
        cout << "YOU WIN !\n\n"; // the user found the secret number
        Start();
     }

        cout << "Too BIG\n";
        life = life - 1;    // -1 to the user's "life"
        cout << "Number of remaining life: " << life << "\n\n";
        GetResults();
     }

     else if (i<j)
     {
