* rndunix.c (my_popen): Make sure that stdin and stderr are

connected to a file.  This is to avoid NetBSD to complain about
set{u,g}id programs invoked with fd 0, 2 closed.  Reported by
Cristian Biere.
(start_gatherer): Likewise. Reordered code.

* configure.ac (NAME_OF_DEV_URANDOM): Don't use /dev/srandom for
NetBSD.  Noted by Christian Biere.
