Windows uses ACLs for evertything. Windows ACLs are very different than POSIX and can be boundlessly complex (as opposed to the fixed set of mode bits in POSIX). Cygwin programs running on a Windows machine kinda live in a separate world from normal Win32 programs running on the machine.<br> <br> Cygwin, as it is a POSIX emulation layer, or actually more like a hosted guest OS layer, has to emulate the POSIX rwxrwxrwx bits by creating such a view "out of thin air" as a "best guess" for existing files. When setting the POSIX mode of a new file created by a Cygwin program, or moduifying it with the Cygwin chmod() "system call", it has to create a potentially quite obscure ACL to get the intended semantic end result as viewed from the Cygwin universe.<br> <br> And when I say obscure, I do mean it; that if you manipulate the same files using both Cygwin chmod etc commands, and normal Windows Explorer protection setting GUI, you can end up in very weird situations.<br> <br> As the DLLs in question that the installer-builder handles are not related to Cygwin at all, have been created by Win32 programs like the MS linker etc, and are to be used by a Win32 program (LibreOffice), I fail to see why any manipulation of their (emulated) Cygwin mode would be needed at all.<br> <br> --tml<br> <br> <br> </blockquote></div><br><br clear="all"><br>-- <br>Regards,<br>Steve Butler<br> </div>
