	Please check in config.log why POSIX check fails. configure script 
tries to build :

   int fd; char *sem = "/test";
   fd = shm_open(sem , O_CREAT | O_RDWR, S_IRUSR | S_IWUSR);
   close(fd);
   shm_unlink(sem);
   fd = sem_open(sem, O_CREAT | O_RDWR, S_IRUSR | S_IWUSR, 0);
   close(fd);
   sem_unlink(sem);
   return(0);

with appropriate headers and this program should run as expected on a 
Linux system.

	Your regression only affects systems that don't have POSIX IPCS and was 
introduced only in 4.1.17. It is fixed in 4.1.18.
