/*
* DIRENT.H (formerly DIRLIB.H)
*
* by M. J. Weinstein Released to public domain 1-Jan-89
*
* Because I have heard that this feature (opendir, readdir, closedir)
* it so useful for programmers coming from UNIX or attempting to port
* UNIX code, and because it is reasonably light weight, I have included
* it in the Mingw32 package. I have also added an implementation of
* rewinddir, seekdir and telldir.
* - Colin Peters <colin@bird.fu.is.saga-u.ac.jp>
