Comment (by Jeff Flinn <jflinn@…>):

 The previously attached filesystem_v3_path_adapter.hpp file allows boost
 filesystem V3 path to be used with file_descriptor* and mapped_file*
 classes. I've tested this on Windows MSVC8 & Mac XCode 3.1.2/gcc 4.0.1
 with utf8 paths. On windows it makes the wide CreateFileW interface
 accessible for opening unicode path'd files. Example usage:

 #include <boost/iostreams/device/mapped_file.hpp>
 #include <boost/iostreams/filesystem_v3_path_adapter.hpp>

 ...

 boost::filesystem::path p(...);

 namespace io = boost::iostreams;

 io::mapped_file_source mf_src(io::filesystem_v3_path_adapter(p));

 ...
