FYI-
Current is now "((void *)0)-clean" and LINT compiles with -Werror.
So things are ready if/when we want to try switching.
These are the files that define NULL:
include/dirent.h
include/locale.h
include/stddef.h
include/stdio.h
include/stdlib.h
include/string.h
include/time.h
include/unistd.h
include/wchar.h
include/rpc/types.h
lib/libstand/stand.h
sys/boot/libstand/stand.h
sys/sys/param.h
