Sorry I don't understand this part of your mail.  Could you *show*
what you did, what you got, and explain what you would have expected?

Any variable defined with `AC_SUBST' in your `' will
be defined in all your `Makefile's.

If you also want to defines rules or if you don't want to define
variables in *all* `Makefile's, you can factor these definitions
in a `Makefile' fragment that you will `include' in all the
relevant `'s.  See the `Include' section of the
manual for the syntax.

Indeed.  There is no "variable inheritance" between `Makefile's.
