>Probably as many millions of lines the C++ standard will use, since its based on boost::filesystem. Not necessarily. A lot of boost contains workarounds for compilers that don't support certain features. Since the standard library will be expected to be used with a known compiler (or at least a new-ish compiler), it doesn't need workarounds for missing C++11 support, etc.
