Try lseek instead of fseek.

fseek is too smart: it won't issue an lseek unless it's really needed,
and it's not simple to force it to do that.  An explicit lseek is much
simpler.

In any case, just by examining the source of fflush you should be able
to see that it doesn't take care to position the file at the end,
before it calls _write.  That is certainly a bug.  (Of course, having
a program which actually shows the bug is a Good Thing ;-)
