We had password aging bugs on Mandriva and I found that when a field of
/etc/shadow contains -1, it gets 32 bits value of -1 on x86_64 even if the field
is long in the struct.
According to the doc it should indeed be empty to disable instead of containing
-1, but well the field is signed and nothing prevents from having a negative value
It used to work and the behavior change broke tests like spw->sp_* != -1 in pam
modules
The change was introduced by
http://repo.or.cz/w/glibc.git/commitdiff/1e545d0185072ac0d4646223d509c3692cbe550a with
a commit message unrelated to this part of the commit
