   As a case in point, let's try to implement an ANSI C memchr:

	   void *memchr(const void *p,int c,size_t n)
	   {	while (n--)
		   {	if (*(const char *)p == c)
				   return (void *) p;	/* !!! */
			   p++;
		   }
		   return NULL;
	   }

Hmmm.  I take it back, this does look like a problem with a constant 'const'.
I'll have to think about this.
