llvm dev - Jun 2010 - [LLVMdev] Bootstrapping llvm

I read on web that llvm compiles itself with clang, but could not find the
instruction to achieve that. I try "./configure CC=clang CXX=clang"
but get link
errors.
How can I do it?

Try using CXX=clang++ instead.  Always use clang++ for C++ code. :)

clang++ does not exist. I tried "CXX=clang -x c++" but fail with
errors, clang
is trying to compile .o files.
"llvm/utils/fpcmp/Release/fpcmp.o:4:2235: warning: ull character
ignored"

with 
./configure --enable-optimized --with-clang=/usr/bin/clang CC=/usr/bin/clang
CXX="/usr/bin/clang -x c++"

Tried clean svn, but fails too. Did I something wrong?
