+/**********************************************************************
+ * Implement dirent-style opendir/readdir/rewinddir/closedir on Win32
+ *
+ * Functions defined are opendir(), readdir(), rewinddir() and
+ * closedir() with the same prototypes as the normal dirent.h
+ * implementation.
+ *
+ * Does not implement telldir(), seekdir(), 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.
