POSIX semaphores on ppc_6xx

[Ben Warren]

Hello,

The cross-compiled glibc that is included in ELDK 4.0 doesn't seem to
have support for POSIX semaphores.  I get the following runtime errors:

   sem_open: Function not implemented

when trying to implement a named semaphore, and 

   sem_init: Function not implemented

when trying to implement an unnamed semaphore.

Does anybody know if POSIX semaphores have been ported to ppc_6xx, and
if so, where I could find a binary copy?

thanks,
Ben
