Thank you, for all the work on this!

I see one smallish issue and a couple of nits: First, now whenever
ChangeLog is touched, the configure recheck will be triggered.  This
isn't a biggie, and if we don't see a simple way around it, then it
should just stay as it is.  (I think this was the reason the stamp file
was originally invented for anyway.)  Second, can we remove the `$target
is up to date' output for all thingies?  Please also update NEWS to
reflect this change.

Thanks again,
Ralf
