 When there is an NTFS mounted volume at some level in the path which is
 passed to `create_directories`. The function fails because of the first
 two checks:
 {{{
 #!div style="font-size: 80%"
   {{{#!c++
   BOOST_FILESYSTEM_DECL
   bool create_directories(const path& p, system::error_code* ec)
   {
     if (p.empty() || exists(p))
     {
       if (!p.empty() && !is_directory(p))
       {
         ...throws/returns an error...
   }}}
 }}}
 For a mounted volume path p is not `empty`, it `exists`, but
 `is_directory(p)` fails. This happens because a mounted volume directory
 is reported by `status(p)` as `file_type::reparse_file`.

 Probably `is_directory()` should be changed to accept existing NTFS
 mounted volumes as already existing directories along the path which is to
 be created.
