Complement of 0 doesn't work as expected (Perl 3, PL41, AT&T 3b1, 3.5.1.4).

The following perl program:
    $foo = 0;

    printf "%o, %x, %o\n", 0666, ~$foo, 0666 & ~$foo;

prints:

    666, 80000000, 0

Complement of 0 should be 0xFFFFFFFF (-1) not 0x80000000.

This is newish behaviour - worked fine at PL 27.  My umask emulator
now makes all the files mode 000.  Yuck.
