+   *  %bitset's index "counts from right to left," to put it very loosely.
+   *
+   *  This behavior is preserved when translating to and from strings.  For

+//         char, signed char, unsigned char			(3)

+//
+// 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

+// or config/cpu when they differ from the generic (read arbitrary)
+// definitions given here.

+
+// These values can be overridden in the target configuration file.
