File size limitations

[Mark Hammond]

If you use the win32api module you can get access to 64 bits of file
size - albiet in an ugly way.  win32api.FindFiles has the high and low
32 bits of the file size - you need to perform the magic to turn these
2 values into a single Python long yourself.

If you use the win32file module, the function win32file.GetFileSize()
should return the file size correctly for huge files - an int object
in the < 2^32 case, and a long object for larger files.

Mark.
