AFAIK it is only these functions which need the special handling.
(and actually I think only couple of them really require it)

And yes, I also did not appreciate this change. I would have
prefered something more visible, like function name change.
Also when I was debugging this in my program, the error was not
"access through zero pointer" but "access through un-initialized
pointer" which I thought is worse debugging wise.

It is of course easy to avoid this problem by using (or copying)
the code from linit.c
