* 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.
