+/**********************************************************************
+ * 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.
