About MacOS; the Windows build process uses a different mechanism

It also say "on UNIX".

Indeed, the MacOS build process uses setup.py, after building python
with a Metroworks project file or some such.

As I said: you'll have to propose a specific change (in form of a
patch) before we can analyse the impact on existing scenarios.

Correct.

That isn't relevant. We should do what's best for Python, not what is
the de factor standard.

I like autoconf, too, but I also know that I spent more time than I
wish trying to figure out why something went wrong in the bowels of
autoconf (in particular when trying to teach it to use the C++
compiler to link python when necessary, not not do so when
unnecessary).

All we need is a more powerful distutils library.
