+/* Virtually everything in the printf() / scanf() test drivers is heavily
+   depending on the platform, i.e. the width of the integer values. To do
+   proper domain tests, we need the limits of the integers (largest and
+   smallest value), which we can get from <limits.h>. But we also need the
+   string representations of these numbers, to the various bases, which of
+   course vary depending on how the platform defines 'int' and 'long'.
