tar and the symlinks

["ZXPLESPAC001, Ext" <ext dot zxplespac001 at astrium dot eads dot net>]

	Hi,
I (tried to) read the FAQ carefully and did'nt find a clue.

The problem is for the packaging of applications that install
some of their files in a directory that is a link.
On NT4 I have a strange behavior: the directory is hidding
the link and the files didn't mix. OK, I know that my english is not
very clear (sorry but I'm french :->), so let's explain with an
example:

1/ I am porting the xlockmore application. This is an X11 program
and after being compiled and configured the X11 resource files
will be installed in $prefix/lib/X11/app-defaults (prefix is /usr/X11R6)
2/ I package the file within a bzip2 compress tar-ball, and this tar 
(for example for the motif GUI xmlock) contains:
usr/
usr/X11R6/
usr/X11R6/bin/
usr/X11R6/bin/xmlock.exe
usr/X11R6/lib/
usr/X11R6/lib/X11/
usr/X11R6/lib/X11/app-defaults/
usr/X11R6/lib/X11/app-defaults/XmLock
3/ after using setup to install this package I have in /usr/X11R6
a directory named app-defaults (which is "hiding" the symlink for the 
initial app-defaults which is a link to /etc/X11/app-defaults and is 
created when installing xorg):

# Before tar xvjf
[zxplespac001@t09258]$ cd /usr/X11R6/lib/X11/

[zxplespac001@t09258]$ ls app-defaults/
XmLock

The real question is : do I have to know when I prepare my package that
some directories are symlinks (it's pretty easy for the app-defaults
problem) ?
Or do untar or setup have to be modified to manage the existence of symlinks
in the directory tree ?
