#12486: system_error_code for thread safe
-----------------------------+------------------------------

 if(!create_directory(root_shared_dir.c_str())){
          error_info info(system_error_code());
          if(info.get_error_code() != already_exists_error){
             throw interprocess_exception(info);
          }
       }

 If the directory exists, get last error is already_exists_error,
 but in the multi thread environment, last_error will be rewritten by
 another thread.

 Whether this can be improved by compiler options?

 test environment: MAC OS
