Indeed, that's what I suggested last time this topic came up. A linear
interface version number doesn't make much sense with a non-linear
development/deployment model...

Of course checking individual interface changes requires coming up with
a good autoconf test for the new interfaces. I hope Emilio already
started an extra thread on this...

Also, what to do with the existing interface version number? Update it
nevertheless for any new interfaces? Leave it there but don't ever
update it? Drop it alltogether?
