From 4d4da5aab936504b2d3eca3146e109630d9093c4 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 19 Apr 2024 14:38:17 +0200 Subject: login: Check default sizes of structs utmp, utmpx, lastlog The default is for ports with a 64-bit time_t. Ports with a 32-bit time_t or with __WORDSIZE_TIME64_COMPAT32=1 need to override it.
