New Revision: 289018
URL: https://svnweb.freebsd.org/changeset/base/289018

Log:
  MFC r284915:
  Make the system queue header file fully usable within C++ programs by
  adding macros to define class lists.
  
  This change is backwards compatible for all use within C and C++
  programs. Only C++ programs will have added support to use the queue
  macros within classes. Previously the queue macros could only be used
  within structures.
  
  The queue.3 manual page has been updated to describe the new
  functionality and some alphabetic sorting has been done while
  at it.
