Why it's can be compiled in GNU/C++, can't compiled in VC++2010 RTM?

In Eclipse(GNU C++.exe -v gcc version 3.4.5 (mingw-vista special r3)) it's two compile error:
Description Resource Path Location Type
initializing argument 1 of void sink_base(std::auto_ptr<Base>)' from result ofstd::auto_ptr<_Tp::operator std::auto_ptr<_Tp1() [with _Tp1 = Base, _Tp = Derived]' auto_ptr_ref_research.cpp auto_ptr_ref_research/auto_ptr_ref_research 190 C/C++ Problem
Description Resource Path Location Type
no matching function for call to `std::auto_ptr::auto_ptr(std::auto_ptr)' auto_ptr_ref_research.cpp auto_ptr_ref_research/auto_ptr_ref_research 190 C/C++ Problem
But it's right in VS2010 RTM.
Questions:
Which compiler stand for the ISO C++ standard?
The content of case 4 is the problem "auto_ptr & auto_ptr_ref want to resolve?"
