You didn't miss anything. These messages go away, if you link explicitly
against libc. But this doesn't help. Maybe it would help to link also with
-g compiled X libs, but this is huge. The author told me he'll see what
he can do for the next release. BTW. Don't link in more things. I did and
got worse messages about inexisting memory faults.
