Why not wrap C++'s <limits> header?

     #include <iostream>
     #include <limits>

     using namespace std;

     int main()
     {
       cout << "Max float: " << numeric_limits<float>::max() << endl;
     }

You can use is_iec559 if you want to ensure that float is 4 bytes,
although I can't imagine that anyone would be using a non-IEEE754
implementation of C++ for compiling Octave. I would expect that there
are already several assumptions in Octave sources that
numeric_limits<float>::is_iec559 is true.
