- * HISTORY
- * $Log: socket.h,v $
- * Revision 2.5 89/03/09 22:07:36 rpd
- * More cleanup.
- *
- * Revision 2.4 89/02/25 17:56:16 gm0w
- * Made CMUCS branches always true, made MACH_VMTP
- * and VICE conditional defines unconditional.
- * [89/02/14 mrt]
- *
- * Revision 2.3 88/08/24 02:44:39 mwyoung
- * Adjusted include file references.
- * [88/08/17 02:23:09 mwyoung]
- *
- * 09-Apr-88 Mike Accetta (mja) at Carnegie-Mellon University
- * Added SO_USEPRIV definition (based on ECE implementation);
- * CS_SOCKET => CMUCS.
- * [ V5.1(XF23) ]
- *
- * 06-Jan-88 Jay Kistler (jjk) at Carnegie Mellon University
