At least in my short test threads seem to work:
[70]Please.tell.me.who.am.I# gcc -Wall -pthread -o thread thread.c
5.000u 0.000s 0:15.80 42.7%     39273+42143k 7+0io 0pf+0w
[71]Please.tell.me.who.am.I# ./thread
hello world
hello world from thread
[72]Please.tell.me.who.am.I# cat thread.c 
#include <pthread.h>
#include <stdint.h>
#include <stdio.h>
#include <unistd.h>

void *
mythread(void *arg)
{
        printf("hello world from thread\n");
        return NULL;
}

int
main(int argc, char *argv[])
{
        printf("hello world\n");
        pthread_t id = 0;
        pthread_create(&id, NULL, mythread, NULL);
        sleep(10);
        return 0;
}
