-// The numeric_limits<> traits document implementation-defined aspects
-// of fundamental arithmetic data types (integers and floating points).
-// From Standard C++ point of view, there are 13 such types:
-//   * integers
-//         bool						        (1)
-//         char, signed char, unsigned char			(3)
-//         short, unsigned short				(2)
-//         int, unsigned					(2)
-//         long, unsigned long					(2)
-//
-//   * floating points
-//         float						(1)
-//         double						(1)
-//         long double						(1)
-//
-// GNU C++ understands (where supported by the host C-library)
-//   * integer
-//         long long, unsigned long long			(2)
-//
-// which brings us to 15 fundamental arithmetic data types in GNU C++.
-//
-//
-// Since a numeric_limits<> is a bit tricky to get right, we rely on
-// an interface composed of macros which should be defined in config/os
-// or config/cpu when they differ from the generic (read arbitrary)
-// definitions given here.
-//
-
-// These values can be overridden in the target configuration file.
-// The default values are appropriate for many 32-bit targets.
-
-// GCC only intrinsically supports modulo integral types.  The only remaining
-// integral exceptional values is division by zero.  Only targets that do not
-// signal division by zero in some "hard to ignore" way should use false.
