Thanks!

I have some comments on the implementation:

  - You seek to end of the file when it is open in the append mode.  I
    wonder whether this is what other implementations do.  My
    references don't seem to imply that opening the file already seeks
    to the end; they only say that before each write the file position
    is set to the end.

  - Instead of adding an fseek to each buffered stdio function (such
    as putc, fwrite, etc.), isn't it better to do that inside _flsbuf,
    which is the only function used by buffered functions to actually
    write to the file?

  - Please put a FIXME comment inside fcntl (where the F_GETFL flag
    should be handled) to say that O_APPEND flag needs to be looked up
    in __file_handle_modes[] and returned to the caller.

Thanks again for working on this.
