You're right - after starting from scratch (unpacking distribution &applying patches), it worked fine. But I still wonder why I didn't see this problem with earlier versions. I unpacked the distribution for 21.2.15 and afterwards applied patches and built for 21.2.16, 21.2.17 and 21.2.18 resp. - for 16 and 17 it was ok, but not for 18 ...

Hmm, this is some kind of dependency problem, it seems. After I recompiled from scratch (i.e., in a totally virgin compilation directory), things were fine. Sorry about that, and maybe a hint for others. -- Cheers =8-} Chipsy Friede, Völkerverständigung und überhaupt blabla
