That makes a lot of sense to me.  I didn't even really notice the RTFatal
call there.  Perhaps Rob can chime in (if he remembers) about why it's
a fatal error rather than a failed open?

And since we have information about why the file failed, it does make sense
to report this.  The only issue is that we will break code that tests:

if fn = -1 then

Granted, this is a very rare occurrence (and even more so on Linux and BSD,
given the max path lengths that they have).  I don't think I've ever 
encountered this problem, myself, although I think I've been close.
If you do anything down in the depths of "My Documents" then it's a definite
possibility.

Maybe one answer is to switch over to the unicode version behind the scenes
for windows, and try it that way?
