No. There is also some problems with file locking if my memory is right, and some package just can't* be implemented on Win32.

We need to provides a complete POSIX emulation not just a binding. -- --|------------------------------------------------------ --| Pascal Obry Team-Ada Member --| 45, rue Gabriel Peri - 78114 Magny Les Hameaux FRANCE --|------------------------------------------------------ --| http://perso.wanadoo.fr/pascal.obry --| "The best way to travel is by means of imagination" --| --| gpg --keyserver wwwkeys.pgp.net --recv-key C1082595
