New Revision: 339648
URL: https://svnweb.freebsd.org/changeset/base/339648

Log:
  ar: report errno on warning/error
  
  Previously ar would report an error like "ar: fatal: Write error"
  without including additional errno information.  Change warnings and
  errors to include archive_errno() so that the user may have some idea
  of the reason for the failure.
