--- Comment #10 from Mike Stump <mikestump at comcast dot net> 2010-12-03 20:17:03 UTC --- Jack says that some of the spurious warnings are fixed in Xcode 3.2.3. I have 3.2.4 on my system. Could you update Xcode and see if any we care about remain. If so, please file a Apple bug report. If fixed, we can simply require the newer Xcode. If it won't work on darwin9, and we care, we could have the .f addition in darwin10.h alone. I don't favor the stripping, but I'g go along with a darwin9 stripper and a darwin10 and later no strip version.
