Including STL in source where a header already calls it

Question

I am running ARtoolkit on Mac OS X Lion (using SDK 10.5, as per ARtoolkit instructions) and would like to include the vector library.

However, it seems that I cannot do this, and don't understand why. At first I thought it was an issue with the toolkit using an old SDK, but in digging through I see that stl_vector.h is included at some point, and when I include vector (or stl_vector for that matter), I get a heap of error messages dumped upon me.

Is there any way around this so that I can use vectors?

Here are my include paths:

#ifdef _WIN32
#  include <windows.h>
#endif
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>

#ifndef __APPLE__
#  include <GL/glut.h>
#else
#  include <GLUT/glut.h>
#endif

#include <AR/gsub.h>
#include <AR/param.h>
#include <AR/ar.h>
#include <AR/video.h>

#include <time.h>
#include "object.h"

#include <vector>

using namespace std;

Here are the errors that I'm seeing...

Ugh. This makes me hate Xcode even more.

In order to fix this, I first converted the project to C++ (renamed files to *.cpp, set compile mode to C++ only), then upgraded the SDK to 10.6 (10.5 originally was the only one to work before converting to C++).

Once this was done, I was able to include vector without any issue. It was just an SDK problem in the end.
