The original large_file spec
< http://ftp.sas.com/standards/large.file/x_open.20Mar96.html >
says in section 3.3.2 that _LARGEFILE64_SOURCE should make
ftello and fseeko visible, just as _LARGEFILE_SOURCE does.

This is not quite the same as saying that _LARGEFILE64_SOURCE should
imply _LARGEFILE_SOURCE, but having the implication is one way to
satisfy that spec.

(Not that anyone should ever actually _use_ _LARGEFILE64_SOURCE.  :-)
