commit 9abdae94c7454c45e02e97e4ed1eb1b1915d13d8
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Apr 19 14:38:17 2024 +0200
login: structs utmp, utmpx, lastlog _TIME_BITS independence (bug 30701)
These structs describe file formats under /var/log, and should not
depend on the definition of _TIME_BITS. This is achieved by
defining __WORDSIZE_TIME64_COMPAT32 to 1 on 32-bit ports that
support 32-bit time_t values (where __time_t is 32 bits).
