Description: Build with swig 4.5.0
 Without this patch, the package FTBFS with swig 4.5.0. This is due to
 the removal of the Python 2 compatibility macros in version 4.5.0.
 According to the SWIG authors, these macros were retained in the
 generated code (pyhead.swg) solely for user typemaps. All typemap
 using these macros are updated to call the Python 3 C API
 directly.
