> Magnus, is this the right fix?

Well, actually msdn states:

"Return Value
 If successful, _setmode returns the previous translation mode. A return
value of -1 indicates an error"

So, shouldn't we be testing for -1 instead of < 0 ?

The thing is probably academic, since _setmode is only supposed to fail
on invalid file handle or invalid mode.
So basically, given our code, it should only fail if filemode is
(O_BINARY | O_TEXT) both flags set.
