This will automatically be taken care of by configure, at least in 2.3 (I
don't remember off-hand if it's also in 2.2.2).  In include/clibrary.h:

/* Large file support.  Use the off_t versions, if available. */
#ifdef HAVE_FTELLO
# define ftell ftello
#endif
#ifdef HAVE_FSEEKO
# define fseek fseeko
#endif

The rest of INN source code should continue to use ftell and fseek as
always for backwards compatibility to those systems that don't have the
off_t versions.  (At some point, as ftello and fseeko become more common,
we should reverse the sense of that correction, but it should be fine for
now.)
