/* This is a variant of config/posix/sem.h for Tru64 UNIX.  The librt

   sem_init implementation assumes int (4-byte) alignment for sem_t, while

   the type only requires short (2-byte) alignment.  This mismatch causes

   lots of unaligned access warnings from the kernel, so enforce that

   alignment.  */
