This means that I still don't have the path comparison right. I've just set up an XP virtual machine and tracked down the problem. os.path.abspath is using short paths, but the argument is a long path, so they don't compare equal.
I see. I'll run again when you found the error.

When I look in the temp folder ( C:\Users\chhenning\AppData\Local\Temp\tmpsiqfhe\ ) there is no zlib subfolder nor any other file/folder.
The temp directory gets deleted. If you want to see what's going on use --preserve.
I run
python zlib.py --verbose --preserve msvc and still there are no files in the tmp folder.
Anything you can spot what is going wrong?
BTW, I think I used you too much of your time today and I can understand when you got better things to do. We can continue any time that's convenient for you.
It's not a problem.
Thanks! Very much appreciated! Christian
