>How-To-Repeat:
stefan@stefan:~ 501 (0)$ cat thread.c
#include <pthread.h>
int
main(void)
{
	pthread_t th;
	pthread_join(th, 0);
	return 0;
}
stefan@stefan:~ 502 (0)$ gcc -kthread -D_THREAD_SAFE thread.c
gcc: unrecognized option `-kthread'
/home/stefan/tmp/ccvI5tGE.o: In function `main':
/home/stefan/tmp/ccvI5tGE.o(.text+0x10): undefined reference to `pthread_join'
