 this is a libstdc++ issue. <limits> appears to specialize
 template<> struct numeric_limits<double> to
 
      static double infinity() throw()
        { return __glibcpp_double_infinity; }
 
 and earlier,
 #ifndef __glibcpp_double_infinity
 #define __glibcpp_double_infinity 0.0
 #endif
 
 on the mainline this is significantly different, using __builtin_huge_val.
