largefile problems

All Unix98 compatible systems are required to support largefile and in fact all the modern unixes/unix-like systems do. However, some have simply dropped the old 32bit limit on file offsets while others have chosen to use 64on32 with a non-const off_t typedef. The latter is rather problematic and this site will tell you about it - and provide you with the knowledge and a tool to handle it, properly.
