Eiskalt DC++ compilation reportedly fails due to std::mutex

Haiku gcc4 have not support std::mutex
How-To-Repeat:
C++ compile the following test case:
{{{
#include <vector>
#include <mutex>
#include <thread>
std::vector<int> x;
std::mutex mutex;
void thread_func1()
{
mutex.lock();
x.push_back(0);
mutex.unlock();
}
void thread_func2()
{
mutex.lock();
x.pop_back();
mutex.unlock();
}
int main()
{
std::thread th1(thread_func1);
std::thread th2(thread_func2);
th1.join();
th2.join();
}
}}}
