The patch fixes this. It also changes two other problems. First it raises an PlatformException if you try to use it with modules which contain compiled C-extensions. Distutils doesn't support crosscompiling.
Ooh, but wouldn't it be cool if I could compile Windows extensions on
and vice-versa... oh, never mind!
I remember having heard that it is possible to cross-compile the windows version of tcl on linux... Maybe someone with more experience than me on could find out?
