Nor is it correct on Linux. As the above link says, _LARGEFILE64_SOURCE
is a hack that was introduced to ease the transition from 32-bit off_t
to 64-bit off_t. The correct idiom is to define _FILE_OFFSET_BITS to 64
before including <sys/types.h> and <sys/stat.h>.
That was *fourteen years ago*, almost to the day. There is *no* excuse
for using this hack today. *Especially* in software that was written
long after that document was published. *Especially* when all you need
to do to get it right is add AC_SYS_LARGEFILE to configure.ac and use
off_t, struct stat and stat() / lstat() (without the "64" suffix) as if
none of this had ever happened.
And yes, I *will* keep harping on this until people Get It.
