Compile errors when including std::mutex before jemalloc.h

This

//CSocket.h
#ifndef __SERVER_CSOCKET_H__
#define __SERVER_CSOCKET_H__

#include "winsock2.h"
#include "ws2tcpip.h"

#include <thread>
#include <stdio.h>
#include <string>

(cpp includes only the header)

//CSocket.cpp
#include "CSocket.h"

produces the following error messages in c:\program files (x86)\microsoft visual studio 12.0\vc\include\ratio

CSocket.cpp

Including std::thread in the .cpp and not in the header solves all errors but I don't know why it doesn't work in the header.

//CSocket.cpp
#include "CSocket.h"
#include <thread>

The only library I am using is jemalloc. Might the error come from including jemalloc.h before mutex not from thread itself?

Solution

I had to #include <mutex> before #include "jemalloc.h" and not afterwards. Works fine now, strange errors though.
