I can easily insert the fix for private with Borland compilers:
>#ifndef BOOST_NO_PRIVATE_IN_AGGREGATE
>    private:
>#endif

However I am not sure about the fix for iteraors:

Looking into the other MSVC headers and finding an existing constant in the
boost config files
how about this one?:
#if !defined(BOOST_MSVC_STD_ITERATOR)
        typedef std::reverse_iterator<iterator> reverse_iterator;
        typedef std::reverse_iterator<const_iterator> const_reverse_iterator;^M
#else^M
        typedef
std::reverse_iterator<iterator,value_type,reference,T*,difference_type>
reverse_iterator;^M
        typedef
std::reverse_iterator<const_iterator,value_type,const_reference,const
T*,difference_type> const_reverse_iterator;^M
#endif

Note that on my MSVC version there are 5! iterator arguments while STLport semms
to provide 4.
Any thoughts?

In addition, I still get errors when I try to compile array1.cpp due to the
initialization.
However, I don't have the actual version (Service Pack 3) installed.
Does it really work with it?
