Build errors for Objects/complexobject.c

[peter.havens at gmail.com]

Okay, after further review, I realized that 'make test' wasn't
completely successful. The test 'test_complex' passed, but 'test_long'
failed:

<snip>
test_long
test test_long crashed -- exceptions.OverflowError: long int too large
to convert to float
</snip>

...do you think my changes caused this failure?
