 Upon successful return from fdopendir(), the file descriptor is under the
 control of the system, and if any attempt is made to close the file
 descriptor, or to modify the state of the associated description other
 than by means of closedir(), readdir(), readdir_r(), or rewinddir(), the
 behavior is undefined.

Just use stat and opendir.  Fixes intel#228.

While here correct the error message.
