And some people find it much better to use:

.../llvm/configure --with-cxx-include-root=/usr/include/c++/4.2 --with-cxx-include-arch=x86_64-linux-gnu --with-cxx-include-32bit-dir=32 --with-cxx-include-64bit-dir=""

i.e. put the same information on the command line instead of patching a 
file. Besides, this also helps in the case where clang finds *several* 
libstdc++ headers and is too greedy to just pick one and stick to it.
