One other thing I remembered about ddb: (SUP'ed Aug 31, but had
the same problem in mid August also.))

    In file included from ../../../../ddb/db_access.c:35:
    machine/db_machdep.h:52: vm/lock.h: No such file or directory
    In file included from ../../../../ddb/db_aout.c:34:
    machine/db_machdep.h:52: vm/lock.h: No such file or directory
    In file included from ../../../../ddb/db_break.c:38:
    machine/db_machdep.h:52: vm/lock.h: No such file or directory
    ^C*** .depend removed

I think I "fixed" this for my "options DDB" test by deleting that
include from db_machdep.h  I doubt that is the correct fix, but as
I remember, it compiled OK.  Should that be sys/lock.h instead,
now that vm/lock.h was (re)moved?
