I've tested in cross-compilation: it builds OK and compiled successfully
the following sample (with -std=c++11).
{{{
#include <iostream>
#include <thread>
#include <mutex>
std::once_flag flag;
void do_once()
{
std::call_once(flag, [](){ std::cout << "Called once" << std::endl;
});
}
int main()
{
std::thread t1(do_once);
std::thread t2(do_once);
std::thread t3(do_once);
std::thread t4(do_once);
t1.join();
t2.join();
t3.join();
t4.join();
}
}}}
