Hallo gnu--developers,

I have two problems with the g++2.3.3:

1.) The compiler does not distinct pre- and postfix versions
    of increment and decrement operators. 
    I think this is a difference to the ARM.

Here a small example:
----------------cut here--------------------------------------------------
#include <iostream.h>

class Integer {
private:
	int _val;
public:
	Integer(int val = 0) {_val = val;}

	int	operator++()	{ _val++; return _val; }
	int	operator++(int)	{ int temp = _val; _val++; return temp; }
	operator int() const	{ return _val; }
};

main()
{
	Integer i(5);
	cout << "i  : " << i << endl;
	cout << "i++: 5 5 6 ok" << endl;
	cout << "i++: " << i << ' ' << i++ << ' ' << i << endl;
	cout << "++i: 6 7 7 ok" << endl;
	cout << "++i: " << i << ' ' << ++i << ' ' << i << endl;
}

----------------cut here--------------------------------------------------
the executable produces the following output:
i  : 5
i++: 5 5 6 ok
i++: 5 6 6
++i: 6 7 7 ok
++i: 6 7 7

the third line shows the problem: gnu ever takes the prefix implementation





2.) The compiler produces an internal error message, if I try to
    use a template class as a member in another class (and there was no
    prior instance of the same template class).
    The cfront has no problems with it. 
    Is it because its additional instantiation pass?

Here is a sample out of a bigger library, where this error occur.
The work around was the external declared dummy of the template.


-------------------------------cut here-----------------------------
class Iterator;

#include <base/generic/tslist.hpp>

#ifdef __GNUG__
extern	TSList<Iterator*> temp_dummy_iter_list;
	// this is a hack
	// to avoid internal Compiler error
#endif


class Collect {
friend class Iterator;
	DECLARE_MEMBERS(Collect);
protected:
	//--- DATA MEMBER ----------------------------------------
	TSList<Iterator*> _active_iter;	// active iterators 
					// on collection
public:

...

};
-------------------------------cut here-----------------------------

Without the additional extern deklaration I got the message:

collect.cc:577: Internal compiler error.
collect.cc:577: Please report this to `bug-g++@prep.ai.mit.edu'.

during compilation of the corresponding source file.
(This is the last line of collect.cc)

The proposed hack seems to avoid this problem.



PS: Sorry. My english is terrible. No flames please.
