member-templates : type conversion doesnt work

[jeroen dobbelaere xe44 7682 <dobbelaj at access dot bel dot alcatel dot be>]

I think I have found a bug :

when working with member templates, I need to have an automatic type
conversion (defined as a member template). 
egcs-1.0 doesn't automagically instantiate the needed convertor.

Example :
-- test.cpp --
#include <iostream.h>

template <class T>
class A
{
public:
  A() {}
  ~A() {}

  template <class T2>
  operator A<T2>() const { cout << "Converted" << endl; return A<T2>(); }

  operator int() const { cout << "Conversion to int" << endl; return 5; }
};

main()
{
  A<int> a1;
  A<long> a2;

  int i;

  i=a1;
  i=a2;

  a2=a1.operator A<long>(); // works
  a2=a1;                    // doesnt work, but should have the same effect
}

--

 g++ -Wall -Weffc++ test2.cpp
/ap/GNUpro/egcs-1.0/include/g++/iostream.h: In method `class _IO_istream_withassign & _IO_istream_withassign::operator =(class _IO_istream_withassign &)':
In file included from test2.cpp:1:
/ap/GNUpro/egcs-1.0/include/g++/iostream.h:237: warning: `operator=' should return a reference to `*this'
/ap/GNUpro/egcs-1.0/include/g++/iostream.h: In method `class _IO_ostream_withassign & _IO_ostream_withassign::operator =(class _IO_ostream_withassign &)':
/ap/GNUpro/egcs-1.0/include/g++/iostream.h:244: warning: `operator=' should return a reference to `*this'
test2.cpp: In function `int main()':
test2.cpp:27: no match for `A<long int> & = A<int> &'
test2.cpp:19: candidates are: A<long int>::operator =(const A<long int> &)

-> egcs should try the A<int>::operator A<long>()

BTW, thanx for providing such a wonderfull product !
