the -lrt Option is very important on hp-ux, since otherwise the following
error messages appear:

/usr/ccs/bin/ld: Unsatisfied symbols:
   sem_post (first referenced in /opt/SDL/lib/libSDL.a(SDL.o)) (code)
   sem_destroy (first referenced in /opt/SDL/lib/libSDL.a(SDL.o)) (code)
   sem_getvalue (first referenced in /opt/SDL/lib/libSDL.a(SDL.o)) (code)
   sem_trywait (first referenced in /opt/SDL/lib/libSDL.a(SDL.o)) (code)
   sem_wait (first referenced in /opt/SDL/lib/libSDL.a(SDL.o)) (code)
   sem_init (first referenced in /opt/SDL/lib/libSDL.a(SDL.o)) (code)
collect2: ld returned 1 exit status

more Information can be found on the man page of sem_post ...

yes
