  Do not directly include files from this subdir, if that's what you've been
doing.  It is private.

  Nope.  Don't define it any way at all, it's private.

#include <sys/types.h>

should give you a valid "off_t".  Whether it does that using an internal
private definition of "_off64_t" or not should not need to bother your code -
the leading "_" indicates implementation-private namespace in the C standard.

    cheers,
