Of course, this still doesn't solve the problem of making sure that the 
_autorebase postinstall script runs whenever the user installs a package 
containing DLLs.  I wonder if we should reconsider Achim's proposal.  If 
I understand correctly, it is something like this (oversimplified):

1. Change autorebase.bat to do an incremental rebase instead of trying 
to do a full rebase.

2. Arrange for autorebase.bat to never be marked as "done".

Achim, please correct me if my oversimplification distorts your 
suggestion too much.
