[uClibc] Named semaphores?

I was looking into an issue that a user reported about the uClinux
implementation that was related to uClibc. They were hoping to use a named
semaphore ( sem_open(), sem_wait(), sem_trywait(), sem_post(), and
sem_close()) to synchronize communication between 2 separate processes.
http://blackfin.uclinux.org/forum/message.php?msg_id=3069
However, in uClibc/libpthread/linuxthreads/semaphore.c the function
sem_open, sem_close, and sem_unlink seems to be just stub functions ,and
set errno to ENOSYS (The function is not supported)
If there are no plans on working on these functions (which is OK), does
anyone else have any ideas to suggest to solve the problem?
Thanks
