Heh, thanks. 🙂

The long version of this is that win32-file uses GetFileSizeEx() behind  
the scenes to get the file size instead of using the ‘size’ member of  
the File::Stat structure. I suppose I should mention that it will only  
work properly on Windows 2000 and later. Hopefully no one is still  
using Windows NT any more. It could be fixed by using \_\_int64 behind  
the scenes iirc but I haven’t looked at it in a while.

One of the things on the TODO list is to redefine the File::Stat  
structure on Windows completely (and submit a patch) because there are  
several other members that should be added (e.g. stuff you can get via  
the GetFileAttributes() function) and a few current ones that need  
fixing, e.g. ‘chardev?’. I’ve been lazy about it, in part because of  
the custom definitions of the Comparable methods such as ‘==’, which is  
a lot of annoying grunt work to implement. This might be easier,  
however, now that I’ve more or less decided to ditch C extensions in  
favor of pure Ruby Win32API packages for most (though not all) of the  
win32utils packages.

In fact, win32-file is the package I plan on reworking into pure Ruby  
form next. 🙂
