This is saying that in order to enable 64-bit addressable ("large") files, there is no special compiler option, but setting _FILE_OFFSET_BITS to 64 enables this functionality. This then causes the build process to use the _FILE_OFFSET_BITS option to enable support for large files. You don't need to do this, the build/configure process has done it for you. This is like saying I need to get to the library: checking if I have a car... no checking if I have a bicycle... yes Wine understands and supports both methods and will use whichever one is available to add that support, or disable the functionality if it cannot. Does this make sense? - Reece
