Maybe.  Making a file bigger than 2GB requires 64-bit indices rather
than 32-bit indices, so apps need to be recompiled with
-D_FILE_OFFSET_BITS=64
No. New kernel headers are unnecessary.

To see if an app is compiled with 64bit file pointers:

stefan:~$ strace -eopen tail -0 /etc/passwd
...stuff edited out...
open("/etc/passwd", O_RDONLY|O_LARGEFILE) = 3

O_LARGEFILE means the program was compiled for >2G files.
