critical impact:

msem_state - unsupported structure member (CrCh69)

Problem description

The msem_state member in the msemaphore structure used by the msem_unlock, msem_remove, msem_lock, and msem_init functions on Tru64 UNIX is incompatible with HP-UX.

The msem_unlock, msem_remove, msem_lock, and msem_init functions perform semaphore operations. On Tru64 UNIX, the definition of the msemaphore structure defines a msem_state member that does not exist on HP-UX. Using this structure member is unsupported.
