not to mention that the preprocessor doesn't understand sizeof(type)...

(note that in the current implementation, the Py_UNICODE_WIDE macro
is used to enable wide storage and disable the surrogate stuff.  it's currently
set if PY_UNICODE_SIZE >= 4, but it might be better to do it the other
way around)
