Как получить TID текущего потока? (библиотека pthread, компилятор g++ 4.6.1 открытый вопрос niXmanу)

#include <windows.h>
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
 
void *BusyWork(void *t) {
   printf("TID= %x\n", pthread_self());
   printf("TID= %x\n", (unsigned int)GetCurrentThreadId ());
   return NULL;
}
 
int main () {
 pthread_t thread;
 pthread_create(&thread, NULL, BusyWork, NULL); 
 getchar ();
}

TID= 1
TID= df0

typedef unsigned int uintptr_t;
typedef uintptr_t pthread_t;

typedef struct {
    void * p;                   /* Pointer to actual object */
    unsigned int x;             /* Extra information - reuse count etc */
} ptw32_handle_t;
 
typedef ptw32_handle_t pthread_t;

   pthread_t pthread_t_ = pthread_self();
unsigned int TID= *(unsigned int*)(pthread_t_.p);
   printf("TID= %x\n", (unsigned int)TID);

//pthread_t WINPTHREAD_API pthread_self(void);

#include <windows.h>
#define pthread_self (pthread_t)GetCurrentThreadId

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
 
void *BusyWork(void *t) {
   pthread_t pthread_t_= pthread_self();
   printf("TID= %x\n", pthread_t_);
   printf("TID= %x\n", pthread_self());
   printf("TID= %x\n", (unsigned int)GetCurrentThreadId ());
   return NULL;
}
 
int main () {
 pthread_t thread;
 pthread_create(&thread, NULL, BusyWork, NULL); 
 getchar ();
}
