Presumably you have UCS4 unicode encoding.  I guess that in ???/include/python/pyconfig.h you
have a line:
#define PY_UNICODE_TYPE long unsigned int
(the 'int' may be missing).

If so, you can work around your problem with casts. Change the line to:
        qstring[i] = QChar(uint(py_unicode_string[i]));
