Re: gtk+-1.2.10

As mentioned in the message, the game itself is owned by games (the
user) and bin (the group).  The permissions on the executable are :
rwxr-xr-x.  (BTW - this is the QT-hack variant)

I won't pretend to know what's going on inside, but I know that the
saved files are owned games:user (user being the primary group of the
user)

Unix NetHack Version 3.3.1 compiled with QT support.

After pulling open the source code and taking a look, nethack does
actually setgid/setuid on a file save:

nethack-3.3.1/src/files.c: line 758-759
        (void) setgid(getgid());
        (void) setuid(getuid());

The game itself doesn't run setuid/setgid so I think this would work
under GTK since GTKs issue is only with having the permissions
setuid/setgid.
