Um. No. There's a reason that things like the macro _LARGE_FILE_API exist. 
While some file systems won't allow larger file sizes, that's generally an FS 
limitation, not an OS limitation. The OSes provide ways to operate on 64-bit 
files on 32-bit systems. If they didn't, it would be impossible to do something 
like read a Blu-ray on a 32-bit system.
