drand48() in cfenvd

[Elizabeth Cassell]

I've been playing with the latest snapshot of cfenvd, and noticed this:
in cfenvd.c, in function RejectAnomaly:

   srand((unsigned int)time(NULL));

   if (drand48() < 0.7) /* 70% chance of using full value - as in learning
policy */
      {
      return new;
      }
   else
      {
      return average+2.0*dev;
      }


drand48() is always returning 0, because it wants to be initalized
with srand48(), not srand().
