OK, that's the problem.

They should be the same. If not, the installation is broken (or at least scripts that rely on this break anywhere else).

So can I have one setup.py for both Python 2.4 and Python 2.5 that does the correct thing when creating a Windows installer for
Python 2.4 (I've used Unicode strings for that until now) and using the upload command with Python CVS (which seems to require a
byte string now)? I'd like to avoid having to use version checks in setup.py.
