  If you need 64-bit types, compile your programs with -D_FILE_OFFSET_BITS=64,
which should be the default on reasonable systems (not sure how common
reasonable systems are nowadays though).
  Please don't use the foobar64_t types, which are a very ugly piece of
glibc bugware and make the code actually incorrect on 32-bit machines.
