Author: des Date: Tue Oct 9 19:27:42 2018 New Revision: 339263 URL: https://svnweb.freebsd.org/changeset/base/339263
Log: Fix portability issues with the Capsicum patch committed in r339216: - Wrap access to pw_change and pw_expire in the appropriate #ifdefs. - Wrap calls to login_cap(3) API in appropriate #ifdefs. - Add wrapper for transferring time_t, which is still only 32 bits wide on FreeBSD i386. - Use a temporary variable to deserialize size_t.
