New patch. It is indeed ucn.zip.
Fixed:
* I think the inclusion of strnicmp will cause more compiler
  problems than do good -- why not simply inline the code in
  the one spot that needs it in unicodeobject.c ?
Went back to the mystrnicmp approach.

* The typedefs in ucnhash.h should probably have the _Py_
  prefix to make it clear that the code is part of the
  Python dist.

Done, altered the generation scripts and regenerated ucnhash.h/.c and fixed up unicodeobject.c
