plugins/mac seems to have dead code. It is not built by Xcode. Let's get rid of it.
Created attachment 236477 [details] Patch
Are these files built when building 32-bit? They might be excluded from 64-bit build, because it doesn't support in-process plug-ins.
I don't think so. Grepping for PluginPackageMac.cpp shows it's only referenced in CMake files (which I added by mistake) and ChangeLogs. If it were built, wouldn't it be in the Xcode files?
Comment on attachment 236477 [details] Patch Fun, seems like these were only used by Qt on Mac. Looks like there are other unused files in WebCore/plugins (I found PluginDataNone.cpp).
Comment on attachment 236477 [details] Patch I'll look into this tomorrow.
Removed PluginDataNone.cpp, too, and mentioned in the committed change log. http://trac.webkit.org/changeset/172535
