Wed Aug 20 15:39:44 1997 Thomas Bushnell, n/BSG * cthreads.c (cthread_body): Wire self before calling user work function.

Default cthread_stack_size to 16 pages if it is zero. Wed Dec 6 14:48:37 1995 Michael I. Bushnell, p/BSG * cprocs.c (condition_unimplies): Take address of (*impp)->next in assignment to IMPP on loop step instruction. Wed Oct 4 16:22:27 1995 Roland McGrath * i386/csw.S (JUMPTARGET): New macro, versions for [PIC] and not. Use it in place of EXT. * Makefile (csw_pic.o): Bogus braindead target from hell removed.
