I think this void exension is just plain broken. Try

#include <u.h>
#include <libc.h>
void foo; void bar;
main() { print("%p, %p\n", &foo, &bar);

It fails in the link stage for me.

I would've tried

    struct PNOTIFY {
	char	nothingness[0];
    };

as it more directly expresses the intent (at least to me) but
that doesn't work either.
