Not acceptable, because it means I have to examine
all the warnings every time I compile to check that
another one hasn't appeared that represents a real
problem.

The most straightforward way to solve the problem
is not to ask for these warnings in the first place.
Or at least it would be if I had a decent amount of
control over what warnings get asked for.

Don't take "make-like" too literally. All I mean
is something organised around a dependency graph
rather than a list of things to do one after the
other.

The nodes in the graph needn't be individual files.
The whole package-to-be-build would be a node,
which would depend on the nodes representing the
.py files.

The specification would probably look fairly
similar in some ways to what you currently pass
to the setup function, i.e. a list of .py files that
go into the package. But the internal structure
would be built out of dependency graph nodes
rather than commands and sub-commands.

I agree that Make itself doesn't handle install-type
operations very well. I think that's partly because
it's too rigidly fixated on a target being a single
file.
