Does anybody know why teh following code taken out of  Stroustrup: Die 
C++ 
Programmiersprache  
Terminates whith ABORT and doen't use the Exception Handler for range 
errors.

Compiler : DJGPP, GCC2.80, CWSDPMI V4.0
---------------------------------------------------------
#include<iostream>

class Range_error
{
public:
    int i;

    Range_error(int ii)
    {
        i=ii;
    }
};

char to_char(int i)
{
    char c=i&static_cast<unsigned char>(-1);
    if (i!=c)throw Range_error(i);
    return(c);
}


void main()
{
    while (true)
        {
            cout<<endl<<"Bitte eine Zahl eingeben ";
            int i;
            cin>>i;
            try 
                {
                    char c =to_char(i);
                    cout<<endl<<"Eingegeben wurde "<<c;
                }
            catch (Range_error x)
                {
                    cerr<<"Huch:to char("<<x.i<<")\n";
                }
        }
}
