commit f9b87aaf109366342777521fe93fe9f795e8f1fa

    Fix sys/time.h build problem due to inconsistent macro usage
    
    	https://sourceware.org/ml/newlib/2015/msg00520.html describes
    	how sys/time.h uses __BSD_VISIBLE while the types used in the
    	affected inline functions are guarded with !_POSIX_SOURCE.
    	Fix that by guarding the type with __BSD_VISIBLE as well.
    
            * libc/include/sys/time.h: Explicitely include sys/cdefs.h.
            * libc/include/sys/types.h: Ditto.  Guard BSD convenience base types
            with __BSD_VISIBLE rather than !_POSIX_SOURCE.
