Ah, I see. Sorry for the noise. I picked up the thread and thought this might be a fact by now.

Since yesterday/today's night, I'm also able to compile again the system. The solution is obscure and a kind of "hoodovoodo" (at least for me). I "updated" backwards the sources via "svn -r 232496 update", then again a simple "make update" in /usr/src. After this procedure the problem vanished. I have no idea what's wrong. Since I thought I might have destroyed my OS by accidentaly interrupting the installation of libc once, were a similar error occured but in another context, I think I'm rather better deleting the /usr/src and doing again an checkout. Something seems very fishy ...
