gcc-4.5.0 Success Story with Freecell Solver

[Diego Iastrubni]

Shlomi:

<code>
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
mkdir -p llvm/tools/clang
svn co http://llvm.org/svn/llvm-project/cfe/trunk llvm/tools/clang
mkdir llvm/cmake-build
cd llvm/cmake-build
ccmake ../
make
export CC=$PWD/bin/clang
export CXX=$PWD/bin/clang++
</code>

Now re-compile your library + test tools.

(PS, If you want to fully bootstrap clang instead of just using stage1 here, 
use this "ugly" shell script to get a "clang built with clang built clang",  
aka stage 3).

Please report how good/bad clang is for your case.
