Macintosh OS X, OTOH, got it right from the start:
506 $ grep fpos_t /usr/include/stdio.h
typedef off_t fpos_t;
typedef int64_t fpos_t;

Of course, this means that special mode is probably not portable to OS X.
And I had trouble trying to build GNU findutils on OS X because that code
sometimes moves an off_t temporarily through a 32-bit integer.
