clang

After reading many questions on here, I decided to give clang a go, and installed the svn version on Ubuntu 12.04 (64bit). I was expecting issues, but it all installed smoothly with no warnings.

I noticed though that when re-running the configure script, if clang/clang++ is in your path it will choose this over gcc/g++ for its own compilation. Is it a good idea to recompile llvm/clang with itself? I know this is absolutely standard with gcc, but I've read that clang's C++ implementation isn't quite good enough yet (maybe this is out of date info...).
