Mike,
   Unfortunately, there is no such -no_warn_compact_unwind flag in the Xcode 3.2.6/4.0 linkers. Since the
-warn_compact_unwind option in the past was set as a default-in option, Apple never bothered to add a flag to
turn it off and forgot to do so (or even to document the fact that the flag was defaulted on now for the
new Xcode releases).
