I'm told that this is fixed in SVID Issue 3.

Meanwhile, I've noticed that the return type from these functions
is a NODE *, where NODE is a completely undocumented internal type.
It really ought to have been the "key" member of the NODE, as indicated
by the documentation.

I think I've figured out why we didn't try to include these in the
ANSI C Standard.
