I'm still going through all the mails from when I was off in
touchpadland now, so hopefully I will have come up with something soon.

But this sounds good to me.  It might be useful to have something like
the below too, so there's no way to claim they didn't know:
diff --git a/configure.ac b/configure.ac
index 39e4df9..2c87bba 100644
