I'd be happy if even the most important packages have been rebuilt for
1.7.  So far the reactions from the package maintainers were somewhat
reticent.

I'm still rather trying to smooth out the upgrade path so that there
are as little as possible manual changes left to the user.  It will
be bumpy nevertheless...

Cool.

The problem so far is the "Cygnus Solutions" registry key and the 
default name of the cygwin dir, C:\cygwin.  When you try to install
1.7, both shouldn't exist.  So what I did is this:

- Rename C:\cygwin to C:\cygwin-1.5.  Change this everywhere in the
  registry.

- My HKCU "Cygnus Solutions" mount table is empty anyway, so it doesn't
  matter.  Rename HKLM "Cygnus Solutions" to "Cygnus Solutions 1.5".

- Install Cygwin 1.7 with setup-1.7.exe into C:\cygwin.

- Rename HKLM "Cygnus Solutions" to "Cygnus Solutions 1.7"

- Rename HKLM "Cygnus Solutions 1.5" back to "Cygnus Solutions".

Since 1.7 doesn't use the above registry key, it doesn't matter for
running 1.7.  Just when calling setup-1.7 for an update, the registry
key rename orgy starts again.

We *really* need a new setup for 1.7 which doesn't access the "Cygnus
Solutions" registry key anymore.
