with
  __linux__
  defined(HAVE_LSEEK64) && defined(HAVE_LSEEK64_PROTOTYPE)
  SIZEOF_OFF_T >= SIZEOF_LONG_LONG
it leads to ext2fs_llseek() doing a "return lseek(fd, offset, origin);"
Which  fails for offsets > 32bit.

Also, with
  __linux__
  !(defined(HAVE_LSEEK64) && defined(HAVE_LSEEK64_PROTOTYPE))
  defined(HAVE_LLSEEK)
  SIZEOF_OFF_T == SIZEOF_LONG_LONG
my_llseek is not defined at all. And there is no need to define
llseek as lseek, as llseek is never used.
Luckily ext2fs_llseek() then does "return lseek(...);"
It would seem that my_llseek should be used in both places.

	This is the new version (1.42.9) of the second extended file
system management programs.

	From time to time, I release new versions of e2fsprogs, to fix
bugs and to make the utilities more robust.  You can always find
information about the latest version at the the e2fsprogs web page,
which is:

	http://e2fsprogs.sourceforge.net

	The INSTALL file has instructions on building and installing
e2fsprogs.  Provisions for building Red Hat RPMs and Debian dpkg files
are supplied as well.

	In case of bugs in these programs, please contact Ted Ts'o at
tytso@mit.edu or tytso@alum.mit.edu.  See the e2fsck man page for
suggestions of what sort of information to include when submitting bug
reports for these programs.
