714 dnl Some versions of SWIG (like 3.0.12) generate code that produces
715 dnl -Wcast-function-type warnings. This warning is present in gcc >= 8. This
716 dnl combo happens on RHEL/Centos 8, for example. Later versions of SWIG (like
717 dnl 4.0.1) have the correct function signatures to not produce this warning.
718 dnl It's simpler to just disable the warning globally.
720 dnl Note that the Debian/Ubuntu SWIG package 3.0.12-2 contains a local patch to
721 dnl fix this (python-fix-function-cast-warnings.patch), so you won't be able to
722 dnl reproduce the warning using that package.
