As I messed with making a custom cron in the late 80s,
remembered the the el_ functions are for event list processing.
But you didn't specify the source of your source, by the hardware
it needs to be of System V heritage. And a lot of that source is hard
to offically come by due to licensing. Good way to view old SVR4 is
to look at OpenIndiana, Illumos, or OpenSolaris code bases that you can
find. You're in luck, as TUHS has a copy, see --
https://www.tuhs.org/cgi-bin/utree.pl?file=OpenSolaris_b135/cmd/cron/elm.c
Look at the Makefile for the other files you need to compile into it too.

Hi. I am trying to compile cron for the 3b2-400 and

on the 3b2-400 after boot up it complains there is corruption
in the crontab for every user lp, sysadm, root and so on.
