commit 9831f98c266a8d56d1bf729b709c08e40375540c
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Apr 19 14:38:17 2024 +0200
login: Check default sizes of structs utmp, utmpx, lastlog
The default <utmp-size.h> 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.
