* src/login.c: "dereferencing type-punned pointer will break strict-aliasing rules", add a variable indirection: ptr_pam_user. * lib/commonio.c: do not initialize the sb stat structure. * lib/pwio.c, lib/shadowio.c, lib/sgroupio.c, lib/groupio.c: initialize the security context if WITH_SELINUX. * lib/nscd.c: The service argument is not const (used in the exec* parameters). This matches with the prototype definition. * src/groupmems.c: Avoid ++i when i is also used in the same line. * src/newusers.c: i is positive every time it is compared. Add cast to unsigned int. * src/nologin.c: Use a main() prototype with no arguments. * libmisc/getdate.y: Initialize the type and value fields of the terminating entry for each TABLE. * libmisc/tz.c: Use "TZ=CST6CDT" as the default timezone.
