Your assumption is correct, and yes, I don't see a simple alternative
either.

You don't need to know, but I meant this:

It is possible but only if you wrap whole rules.  You cannot wrap parts.
See depend2.am for examples.

No.

Ah ok, I wasn't aware of that.

Not if you look in git master of Automake.

Both are accepted.

Respective bits to auto{conf,address@hidden, please.
