Re: [OT] Re: [Mingw-users] POSIX subsystem (was: Building DLL's with MinGW on Windows XP)

We meant differently with the word "activated". Sorry that my reading does
not conform to Microsoft's documentation. If you replace my "activated" with
"activatable", they should agree.

Also notice that my original wording was that "the POSIX subsystem on
Windows NT (including 2000 and XP) is not normally activated unless one uses
a POSIX executable (I remember there are some in the Resource Kit of Windows
NT). It is often recommended to disable the POSIX and OS2 subsystem ...".

Best regards,

  Not according to NT4 Workstation Documentation.  That states that the
posix subystem is not activated unless a posix command, recognizable by
those files within the c:\winnt\system32 (those that you list below).

   Yes, but doesn't mean they will run.  You might want to check your
task manager under NT4 Workstation the next time you attempt to invoke
the posix subsystem.  All you need to do is open command prompt, and
type a posix command, such as "ls".  You will see for yourself.

   The posix subsystem runs only as a protected server, it will not run
otherwise.  Also, if you completely uninstall your NT4 Workstation, and
reinstall it, and then attempt to run a posix command, it will fail.  In
other words, Posix subsystem is not activated by default for NT4
Workstations.

  Posix subsystem is only activated when all of the posix related
services are on the system path, including the posix commands.  You also
have to have the binutils available before posix subsystem will run and
they must be on the system path.  Otherwise Posix commands fail.
