Hmm.  So, as a question of include-file naming, does "sys/" imply
that it's tied to the system kernel in some sense?  I mean, why
would this imply "queue.h", while the earlier macros imply
"sys/queue.h"?

(I'm just wondering.  Certainly the changes seem fine to me.  But
if I'm using the older macros in some userland program, should I
reference <queue.h> or <sys/queue.h>? )
