You are confusing things here.
A package needs a unit, that has a uses clause to let the compiler
compile all units of the package. A design time package also needs to
register its Register procedures.
By default this is done by an auto generated unit. You can do this
with an unit of your own if you prefer.
This unit can also be added automatically to the program, to make sure
that all initialization sections of the package are called.
This is what you mean with "the unit managing the package must (or
mustn't) be added to the program using that package". By default
this is not done and this setting has nothing to do whether the unit is
compiled aka the $warn.

Sharing ppu can be done easily with macros too and packages can
compile ppu for each project as well. You are missing the point of
packages.
The purpose of packages is to make sharing code easier by separating
the compilation of program and package sources. For example you can add,
rename directories in a package without affecting all programs. You can
play around with compiler flags in your program with less worrying that
packages are affected.
Using macros requires good knowledge of every package you use. As far
as I know you, Graeme, created or maintain all packages you use. In that
case packages are indeed just shared directories of your own sources
and macros might be the better solution.

The IDE automatically adds this line to the auto generated package unit.

I changed it now, so it if this $warn is the only difference it does not
update the file.

Hint: You can use the TortoiseSVN 'revert' function for that.

It is always the package unit - I don't know if this is the correct 
name, I mean the unit which has the same name as the lkp file and which 
is autocreated, its first lines say: "This file was automatically 
created by Lazarus. Do not edit!   This source is only used to compile 
and install the package."


I wonder, since this file is autocreated, why must it be under version 
control then?


Not all packages show this warning at the moment. But I must say that I 
did have the situation that all Lazarus packages in the components 
folder were "red". I could fix this by a clean install, just like Bart 
said. Now most (or all?) of the my third-party packages still have this 
issue: bgrabitmap, zeos, luipack, lazbarcodes, lclextensions, 
virtualtreeview_new etc.

I see the same thing here with Lazarus v1.7. It is annoying for the SCM,
but I think I figured out the reasoning for that line. Lazarus packages
have somewhere a setting that says the unit managing the package must
(or mustn't) be added to the program using that package. I guess it
helps with forcing FPC to compile all units in question. I always delete
that, as I like my uses clause clean.

My suggestion (and personal solution) is to shy away from using packages
at all. I used to believe they were the best feature of Lazarus after I
moved from Delphi years back. I don't think that any more.

Project templates and macros in settings have simplified my life a lot.
My hard drives have plenty of space for non-shared [between projects]
compiled units too. Lazarus simply has too many "automated
functionality" these days that simply annoy.


Are you really sure that this message is useful in this thread? Please 
stop this.

Had that before.
A clean build of Lazarus then fixed it, the lines were left in.
(Well, IIRC I had to do that twice for some, inexplainable reason it
didn't work the first time)

[Lazarus] {$warn 5023 off: No warning about unused units}

[Werner Pamler]

Since some time, the TurtoiseSVN overlay icons of some of the packages 
which I loaded from svn have become practically useless. It is always 
the autogenerated package unit which is marked by a red overlay icon as 
being out of date. When I open the unit I see that the line


{$warn 5023 off : no warning about unused units}

has been added to the unit header. Deleting the unit, updating it from 
the svn repository fixes it for the moment, the "no warning about unused 
units" line is gone, and the overlay icon is green. But when I open the 
package and recompile it the line comes back, and the icon turns read again.


There must be something in my Lazarus settings which inserts this line.

Could anybody give me a hint where to look?

I am having this issue with Laz trunk / fpc 3.0 on Win7.
