Windoze if FUBAR
** Lets face it, windoze if FUBAR!!!
** For some reason, I have to call _lseeki64() TWICE to get
** to the end of the file.
** This might have been avoided if windows had implemented
** the POSIX standard function fsync() but NO, that would
** have been too easy.
** I am VERY close to saying that windoze will no longer be
** supported by libsndfile and changing the license to GPL
** at the same time.
