I'm not sure, but wasn't this kind of warning moved
from under '-Wall' to under '-W'?

gcc 3.3.2's manpage says:

-W Print extra warning messages for these events:


o A comparison between signed and unsigned values
could produce an incorrect result when the signed
value is converted to unsigned. (But don't warn
if -Wno-sign-compare is also specified.)
