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
