configure uses AC_SYS_LARGEFILE to determine whether to define
_FILE_OFFSET_BITS=64, in which case fseeko64 and lseek64 are used in
place of fseeko and lseek.  However, this is technically backwards, as
_FILE_OFFSET_BITS=64 is supposed to be used to override fseeko etc. with
64-bit variants even on 32-bit systems, and the explicit 64 variants are
correctly guarded by _LARGEFILE64_SOURCE.  This results in implicit
declarations in 32-bit systems (i686) which recently became errors.
