/**********************************************************************
* Implement dirent-style opendir/readdir/closedir on Window 95/NT
*
* Functions defined are opendir(), readdir() and closedir() with the
* same prototypes as the normal dirent.h implementation.
*
* Does not implement telldir(), seekdir(), rewinddir() or scandir().
* The dirent struct is compatible with Unix, except that d_ino is
* always 1 and d_off is made up as we go along.
*
* The DIR typedef is not compatible with Unix.
