/* We have a severe problem here. The ISO C standard
contradicts itself in explaining the effect of the %n
format in `scanf'. While in ISO C:1990 and the ISO C
Amendement 1:1995 the result is described as
Execution of a %n directive does not effect the
assignment count returned at the completion of
execution of the f(w)scanf function.
in ISO C Corrigendum 1:1994 the following was added:
Subclause 7.9.6.2
Add the following fourth example:
In:
#include <stdio.h>
int d1, d2, n1, n2, i;
i = sscanf("123", "%d%n%n%d", &d1, &n1, &n2, &d2);
the value 123 is assigned to d1 and the value3 to n1.
Because %n can never get an input failure the value
of 3 is also assigned to n2. The value of d2 is not
affected. The value 3 is assigned to i.
We go for now with the historically correct code fro ISO C,
i.e., we don't count the %n assignments. When it ever
