Again, -Wconversion does nothing to help with 64-bit coding on the version of gcc that Apple is currently shipping. Read the man page if you don't believe it. The useful one for this purpose is -Wshorten-64-to-32. That Apple document is either wrong or referring to a different version of gcc than the one my man page is talking about.
