As Steve Greenland suggested, you are confusing AC_SYS_LARGEFILE
and AC_SYS_LONG_FILE_NAMES.  From the Autoconf manual:

 - Macro: AC_SYS_LARGEFILE
     Arrange for large-file support(1).  On some hosts, one must use
     special compiler options to build programs that can access large
     files.  Append any such options to the output variable `CC'.
     Define `_FILE_OFFSET_BITS' and `_LARGE_FILES' if necessary.

 - Macro: AC_SYS_LONG_FILE_NAMES
     If the system supports file names longer than 14 characters, define
     `HAVE_LONG_FILE_NAMES'.

I didn't look at your log file, so there could be something else
going on too.
