 '''Name lookup changes'''

 GCC 4.3 by default no longer accepts code such as


 {{{
 template <class _Tp> class auto_ptr {};
 template <class _Tp>
 struct counted_ptr
 {
   auto_ptr<_Tp> auto_ptr();
 };
 }}}


 but will issue the diagnostic

 error: declaration of 'auto_ptr<_Tp> counted_ptr<_Tp>::auto_ptr()'
 error: changes meaning of 'auto_ptr' from 'class auto_ptr<_Tp>'

 The reference to struct auto_ptr needs to be qualified here, or the name
 of the member function changed to be unambiguous.

 {{{

 template <class _Tp> class auto_ptr {};
 template <class _Tp>
 struct counted_ptr
 {
   ::auto_ptr<_Tp> auto_ptr();
 };
 }}}


 In addition, -fpermissive can be used as a temporary workaround to convert
 the error into a warning until the code is fixed. Note that then in some
 case name lookup will not be standard conforming.
