commit 836d43b98973e0845b739ff5d3aad3af09dc7d0f

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).
