about istream_iterator

[ben]

Is istream_iterator<> and ostream_iterator<> supposed NOT to be included in
<iostream>? The following example compiles in VC 7.1 but not with gcc 3.4.3

#include <iostream>
#include <deque>
#include <algorithm>

int main()
{
using namespace std;

deque<int> ls;
copy(istream_iterator<int>(cin), istream_iterator<int>(),
back_inserter(ls));
sort(ls.begin(), ls.end());
copy(ls.begin(), ls.end(), ostream_iterator<int>(cout));
return 0;
}

<iostream> is not prohibited from declaring those
types, but neither is it required to do so.

The header which will guarantee the declarations
of 'istream_iterator' and 'ostream_iterator

copy(ls.begin(), ls.end(), ostream_iterator<int>(cout));
return 0;
