+            [Python] #2277 Define PY_SSIZE_T_CLEAN macro before #include "Python.h" as
+            recommended in Python 3.7 and later.
+
+            To avoid this macro definition, add the following to your interface file so
+            that SWIG_NO_PY_SSIZE_T_CLEAN is defined at the beginning of the C++ wrappers:
+
+              %begin %{
+              #define SWIG_NO_PY_SSIZE_T_CLEAN
+              %}
