This isn't enough for new installers, either :(  I have an MSI-based
InstallShield installer that's looking for shdocvw.dll to see if IE6 is
installed.  (It isn't, but that's how it's looking for it.)

Trouble is, how would this work with the native/builtin thing?  Right now
all our builtins don't live in the system directory, so we can always
override whatever native dll happens to get dropped there.  If we put a
little stub PE header in there, what's to stop an installer from
overwriting it?  Or, would this cause a problem?

Well, if the little stub is overwritten by a correct native DLL then 
there is no problem at all. If some install overwrites it with an older 
version than what apps expect (or Wine provides) then that might be a 
problem, but that's just the generic DLL Hell the windows library design 
implies.

Windows XPXPas this nice new feature of Side-by-Side AsAssemblieshat is a .Net concept. It
combined with Windows File Protection has in effect ended DLDLLell. Maybe we should look at
implementing some sort of side-by-side system in Wine.

Thanks
