    Problems porting from MSVC++ to Apple Developer Tools

    I have code that compiles with no warnings on MSVC++ 6.0, and am trying to port it for a friend running the compiler in the Project Builder app for Mac OS. When he tries to compile, he gets an error
    main.cpp:241: no match for `Bint& - Bint' operator
    where I've indicated line 241 in the code below.

    Here is the implementation of the function giving me problems:
    Code:
    bool Bint::operator~(void)
    {
    	int digit;
    	for(int i=0;i<size;i++)
    	{
    		digit=digits[i];
    		Bint& temp=Bint(&digit,1,base);
    		*this=this->operator-(temp); //Subtract each digit, one at a time,
    		//from the number
    	}
    	if(size==2 && digits[0]==0) //Check for 0
    		return false;
    	return true;
    }
    Line 241 is the one beginning with *this=this...

    Here is the class definition:
    Code:
    class Bint
    {
    public:
    	Bint(const char *init, int base);
    	Bint(void);
    	Bint&(Bint &init);
    	~Bint();
    	int GetSize(void) const {return size-1;};
    	Bint operator+(Bint &second) const;
    	Bint operator-(Bint &second) const;
    	Bint operator=(Bint &second);
    	bool operator~(void);
    	friend ostream& operator<< ( ostream& os, Bint num);
    
    private:
    	Bint(const int *init, int size, int base);
    	int *digits;
    	int base;
    	int size;
    };
    Does anybody have any ideas what my mistake is?

    Replace that line with
    Code:
    *this = *this - temp; //Subtract each digit, one at a time,
    gg
