711 dnl combo happens on RHEL/Centos 8, for example. Later versions of SWIG (like
712 dnl 4.0.1) have the correct function signatures to not produce this warning.
713 dnl It's simpler to just disable the warning globally.
715 dnl Note that the Debian/Ubuntu SWIG package 3.0.12-2 contains a local patch to
716 dnl fix this (python-fix-function-cast-warnings.patch), so you won't be able to
717 dnl reproduce the warning using that package.
