The mode of operation of clang under discussion is not a 'normal' mode, but 
a mode in which clang and gcc aare both used, if I understood what Eike told 
me.

I what is being discussed is either this:

 http://dragonegg.llvm.org/

or this:
 
 http://llvm.org/releases/2.9/docs/CommandGuide/html/llvmgcc.html

which I think is deprecated.

Eike, can you provide (a link to) more information on the problem you 
described to me before?

Thanks,

Steve.
