	bcopy.  This name isn't used outside obstack.h and so no problems
	from using the memcpy function in a file including obstack.h can
	result.

+		 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
+		 should proof to be wrong just remove the #ifdef above.  */
