+Subject: [PATCH] python: update for SWIG 4.5
+
+SWIG 4.5.0 removed Python 2 compatibility macros (PyInt_, PyString_, SWIG_Python_str_*)
+from its runtime header pyhead.swg (see commit [1]). These macros mapped old Python 2
+C API names to their Python 3 equivalents. Packages that reference them in custom SWIG
+typemaps or pre-generated wrapper code now fail to compile.
+
+This patch replaces all occurrences with the corresponding Python 3 C API functions.
+The replacements are safe since the macros were already aliased to these exact functions
+in SWIG's Python 3 code path.
