    Add feature macro for NetBSD
    
    NetBSD does not expose all of its own stuff with _BSD_SOURCE.  For
    that, you also need _NETBSD_SOURCE.
    
    Without this, "NSIG" (and probably other things too) is undefined,
    because it's declared conditionally in sys/signal.h on _NETBSD_SOURCE.

     interrupted by a signal, we now retry (thanks to Joerg Wittenberger).
