Hi Trevor,
I just substituted like this

  if (ignore) {
    minx = 1e+308; //orig: std::numeric_limits<double>::max();
    maxx = 1e-308; //orig: std::numeric_limits<double>::min();
  }

and didn't have any problem. 
I running debian, where 2.95 is still the "standard". Maybe this could be 
changed in CVS - just for one more year or so ;-)

Cheers,
