As far as I can remember the semantics of an inline function is supposed to be
*EXACTLY* the same as if it were not declaread as inline. This, however, seems
not to be the case in most C++ 1.2 implementations. I only tried the following
program on an Apollo using Domain C++ and an Ultrix Vax with designer C++,
but it should reproduce on most other C++ 1.2 compilers (those based on the 
AT&T version) as well:

---------------------------------------------------------------------------

#include <stdio.h>

struct loop { struct loop *next; };

struct loop loopback = { &loopback } ;

/* also try this without inline: */
inline overkill ( struct loop * x)
{
	printf("%ul\n",x);  /* this should print the same */ 
	x->next = NULL;
	printf("%ul\n",x); /* as this, ????? :-) */
}


main(){
	overkill(loopback.next);
}
