Subject: useradd.c: Fix undeclared subuid_count when not using subids
X-Git-Tag: 4.10~44^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=049b08481acc2040e2079ae06e64d0bb36326528;p=thirdparty%2Fshadow.git

useradd.c: Fix undeclared subuid_count when not using subids

subuid_count won't get used by usr_update(), but since we're passing it
as an argument we have to make sure it's always defined.  So just define
it as pre-set to 0.

Closes #402
