The zlib site recommends against using versions older than 1.2.3 due to
security issues.

I could check if ZLIB_VERNUM >= 0x1230, and abort configure accordingly,
to make sure kaffe is built with zlib 1.2.3 or higher.
"Version 1.2.3 eliminates potential security vulnerabilities in zlib
1.2.1 and 1.2.2, so all users of those versions should upgrade immediately."
