| Why is it that most of you insist on macros instead of const ints? Afaik gcc 
| will generate the exact same code for:

I'm not sure to fully undertand your question, but here is what will
happen in effect:

	// #define goes here....

	template<>
	struct numeric_limits<int>  {
	  const bool is_specialized = true;
	
	  static const int digits = __glibcpp_int_digits;
	  //  and so on...
