Sorry, I'm confused, and the documentation snippet didn't really
enlighten me :(

I really thought that your patch was purely static, i.e., only from
.am to .in, requiring no special feature from Make.  You seem to say
in the first paragraph above that it's only the case of *this*
example, but I'm now failing to see in which cases you would not
depend upon the underlying Make.

We are hitting a limit (assumptions over Make) which is out of my
competence.  Only Tom and Alexandre may make such decision...
