When I see this code I cannot help thinking of something like:

Even shorter:

version(Solaris)
   enum PTHREAD_BARRIER_SERIAL_THREAD = -2;
else
   enum PTHREAD_BARRIER_SERIAL_THREAD = -1;
        
int pthread_barrier_destroy(pthread_barrier_t*);

int pthread_barrier_wait(pthread_barrier_t*);
int pthread_barrierattr_destroy(pthread_barrierattr_t*);
int pthread_barrierattr_getpshared(in pthread_barrierattr_t*, 
int*);
int pthread_barrierattr_init(pthread_barrierattr_t*);
int pthread_barrierattr_setpshared(pthread_barrierattr_t*, int);
