Tried, that code ... And got a error (which I not really understand,  
yet)
|| > g++ -g -O0 toy-example26.cpp -o toy-example26 \

Note,   `/Users/albert/NoTimeMachine/LLCM_Clang/llvm-trunk/BUILD/Debug/ 
bin/llvm-config --cppflags --ldflags --libs core jit native` gives

Trying to build with other version/Build (PreBuild one, Debug-version,  
or trunk) give same error and simular values for llvm-config output  
(same, but for the path)

Any Idea? --THANKS
