Re: Deleting directory on Windows.

  Thanks for the code! I will modify to fit my needs.

   The bug is actually documented on the remove(3) man page.

Except from the GNU remove(3) man page.

"NOTE
       Under libc4 and libc5, remove was an alias for unlink (and
       hence would not remove directories)."


  What happens on Windows is that if I use remove() to remove a dir, I get a
permission denied. If I use rmdir(), it works fine. 

  Thanks again for the help.

Harrring.
