Hi,
Building Subversion trunk with SWIG 4 on Windows, the following errors occur:

Investigating the issue, I noticed generated SWIG_PY_OPTS differs between Unix
and Windows.
<SWIG_PY_OPTS>-python -py3</SWIG_PY_OPTS>
should be "-python -py3 -nofastunpack" when SWIG 4 is used.
After attached patch, no differences of SWIG_PY_OPTS between Unix and Windows.
