Description:
When using g++ 4.6.2 (on x86_64) to compile following code:

---------------------------------

#include <thread>
#include <chrono>

int main() {
std::this_thread::sleep_for(std::chrono::seconds(1));
return 0;
}

---------------------------------

there is a strange error:
./main.cpp:5:3: error: ‘sleep_for’ is not a member of ‘std::this_thread’

Additional info:
core/gcc 4.6.2-3:

g++ --version
