That was from an earlier version of the SGI STL.  We commented out
auto_ptr in that version for exactly the reason given in the comment:
at that time the details were still under discussion by the committee,
and we didn't want to provide an auto_ptr until we knew what the final
version would be.

That's just history, though.  The C++ standard is now final, and the
auto_ptr design issues have been resolved.  The current release of the
SGI STL (3.13) does include a standard-conforming auto_ptr.

Hi, everybody

I have find that standard tamplate library implemented by gnu
(libstdc++-2.8.1.1)  doesn't include the auto_ptr,
like other STL implementations do. For example SGI
(http://www.sgi.com/Technology/STL) or STLPORT
(http://www.stlport.org/).

I ask why gnu doesn't include auto_ptr.

I also ask if it is better to wait a new version of  libstdc++ or change
to an other STL library implementation, SGI o STLPORT.

This is the portion of the libstdc++-2.8.1.1 file containing the
auto_ptr code ()  commented:
........
    // Note: auto_ptr is commented out in this release because the
details
    //  of the interface are still being discussed by the C++
standardization
    //  committee.  It will be included once the iterface is finalized.

    #if 0
    #if defined(_MUTABLE_IS_KEYWORD) && defined(_EXPLICIT_IS_KEYWORD) &&
\
        defined(__STL_MEMBER_TEMPLATES)

    __STL_BEGIN_NAMESPACE

    template <class X> class auto_ptr {
    private:
      X* ptr;
      mutable bool owns;
.........

Thanks.
