Sorry, 

In posting the tanh bug, I neglected to modify the sinh code (other
than the name of the function).  The correct version follows:

double tanh(double x)
{

  const double epos,eneg;
  if(x>=0.0){ 
    epos=exp(x);
    eneg=1.0/epos;
  }
  else { 
    eneg=exp(-x); 
    epos=1.0/eneg;
  }
    return (epos-eneg)/(epos+eneg);
}

Sorry for any inconvenience.
