Um, we already do this, unless I misunderstand your proposal. For any
2.x (and even 1.x) version, "make altinstall" installs only pythonx.y,
and "make install" creates a link to it named "python". For 3.0,
"install" is equal to "altinstall" because making 3.0 the default is
not realistic at this time. At some point in the future we can revisit
this.

And have been forever.

Ah, Windows. Can you file a bug about this? I think only MvL can do
something about this.
