Without _GNU_SOURCE set, Linux should fail to declare pread at all, at
which point INN should declare it internally using off_t.  Since this is
done after _FILE_OFFSET_BITS is set, this should give the 64-bit off_t.

Do you know why this isn't happening?  Is configure reporting that it
found a declaration for pread?
