New Revision: 56309

Modified:
   python/branches/py3k-struni/Modules/_ctypes/_ctypes.c
   python/branches/py3k-struni/Modules/_ctypes/ctypes.h
Log:
Py_USING_UNICODE is no longer defined on Windows (on posix it is still
in pyconfig.h).  Remove the workaround for the broken (in Python 2.3)
PyUnicode_(From|As)WideChar functions.
