Trying to build the latest, 8.18.1, returns:

The same happens if I try to build 8.17.2 - which is the version I built and have been using for 5 years. I don't even understand the error. Slackware current, Kernel 6.16.1. Slackbuilds seems to have abandoned sendmail. This happens even with unmodified source.

A redditor pointed me to a patch https://github.com/gentoo/gentoo/blo..._strtoll.patch

There's another patch to get mailstats to build: https://github.com/gentoo/gentoo/blo...23-ctime.patch

The 8.18.1.10 snapshot doesn't have this problem.
