When commenting out the wrapping
=2Eif defined(USE_CLANG)
=2Eendif
construct, as suffested by Olivier, it works. I gues I found my mistake: =
From an earlier attempt of building FreeBSD with clang, I placed the=20
WIKI suggestions into /etc/src.conf and I never recalled this. I delete=20
it and try again ...
On my lab's box, same OS, same revision, nearly same hardware, building=20
world/kernel worked fine even with the 'switch' - but there wasn't=20
/etc/src.conf.
Thanks for the hints. I'll report again.

Oliver
