        <pre>This is particularly in view of the discussion about moving to c++11.

In a OS X 10.9, "xcode-select --install" puts only libstdc++ in /usr/include.
The result is:

$ cat test.cpp
#include <iostream>
$ ./build/bin/clang -stdlib=libstdc++ -S test.cpp
$ ./build/bin/clang  -S test.cpp
test.cpp:1:10: fatal error: 'iostream' file not found
#include <iostream>
         ^
1 error generated.

The xcode provided clang can find the include
(/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/iostream).</pre>
