Building 2.4.11 still fails with type mismatch

Sorry issue #732 is still not fixed. Even building 2.4.11 still fails with same error.

Note that OBS uses pretty strict compiler options: https://build.opensuse.org/package/live_build_log/home:stroeder:iam/apache2-mod_auth_openidc/openSUSE_Tumbleweed/x86_64
