Are there?

I would not qualify autoconf/automake of 'unrelated' but 'essential' tools, and
would never call 'nuisance' the fact that you ask a user to be in the 'conditions'
that guarantee a proper build. I can not guarantee this proper build with earlier
versions, I don't have time neither any wish to maintain older version of these
essential tools.

Are you aware of any incompatibilities between 2.69 and earlier 2.x version(s) of
autoconf?
