 create_directories doesn't handle correctly path bigger than MAX_PATH:

 if I try

 boost::filesystem::wpath
 path(L"c:\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=");

 boost::filesystem::create_directories(path);

 throws some error and it created folder structure to MAX_PATH

 if I try

 boost::filesystem::wpath
 path(L"\\\\?\\c:\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=\\1234567890\\abcdefghijklmnopqrstuvwxyz~!@#$%^&()_+-=");

 boost::filesystem::create_directories(path);

 throws 3 errors (can't handle: "//?", "//?/", "//?/c:")
 but the full path is created

 After, I try to delete "c:\\1234567890", remove_all failed.
 if I try to delete \\\\?\\"c:\\1234567890", remove_all succeeded.
