gnu compiler : ostream_iterator problem

[killerbot]

Anyone aware of the following problem with the gnu compiler (or just the mingw port) ??

The following simple code does not compile :

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

int main()
{
   vector<int> coll;
   coll.push_back(10);
   coll.push_back(20);
   coll.push_back(30);
   copy(coll.begin(), coll.end(), ostream_iterator<int>(cout, "\n"));
   return 0;
} // end of main

I get :

main.cpp: In function `int main()':
main.cpp:13: error: `ostream_iterator' undeclared (first use this function)
main.cpp:13: error: (Each undeclared identifier is reported only once for each function it appears in.)
main.cpp:13: error: expected primary-expression before "int"
Process terminated with status 1 (0 minutes, 0 seconds)
3 errors, 0 warnings
 

I does build with M$ VC 2005, and according tothe book The C++ Standard Library (Josuttis), page 107, this is correct code.

IS there some part not supported by either :
 - GNU C++ compiler
 - MingW port


kind regards,

also with Digital Mars I get the error :

dmc.exe -mn -c       -I"C:\dm\stlport\stlport" -I"C:\dm\include" -o.Marsobjs\main.o main.cpp
   copy(coll.begin(), coll.end(), ostream_iterator<int>(cout, "\n"));
                                                  ^

Add #include <iterator> and it 'll work
