What "binaries" are you talking about?
AFAIK, C extensions should fail loading when they have the wrong UCS2/4 setting.
That's the reason we have all those #define's in unicodeobject.h: the actual
function names end up being different and, therefore, are not found when linking.

For information, all Mandriva versions I've used until now have had their
Python's built with UCS2 (maxunicode == 65535).
