    What a nightmare for the maintainer(s).

It could be automated (even if the fragments are physically present in
all the files).  E.g.,
### ac_included foo begins here
... foo content here ...
### ac_included foo ends here

And a script could check/replace what's between the ### lines with the
content of the foo master file.

But it's certainly something to avoid if possible.  Your splitting the
Makefile seems clean in comparison :).
