Are named posix semaphores not implemented?

i tried to port a program using PCBSD based on FreeBSD 7.1
and the small test program

#include <semaphore>
#include <stdio.h>
#include <fcntl.h>

int main() {
   sem_t* s = sem_open("foobar", O_CREAT|O_EXCL);
   if (s == SEM_FAILED) perror("sem_open");

raises a "bad system call 12" signal
But from the manpage of sem_open tells me that it should
be there since FreeBSD 5.0?

Please don't tell me that i have to rewrite the code.

Best regards,
