pthreads problems

[aindros]

Hello, I have problems running cmake-vs2013-32bit.bat, after configuring Visual Studio 2013 to work with pthreads, I get this error:

Performing C SOURCE FILE Test CMAKE_HAVE_LIBC_PTHREAD failed with the following output:

Source file was:
#include <pthread.h>

void* test_func(void* data)
{
  return data;
}

int main(void)
{
  pthread_t thread;
  pthread_create(&thread, NULL, test_func, NULL);
  pthread_detach(thread);
  pthread_cancel(thread);
  pthread_join(thread, NULL);
  pthread_atfork(NULL, NULL, NULL);
  pthread_exit(NULL);

  return 0;
}

I have pasted that code inside an empty project on VIsual Studio 2013 and I can compile and execute that without problems (after commenting _pthreadatfork() because I have noticed that there is no definition for that function in pthread.h).

Any suggestions?
