Why do you think it is necessary to test if the old file exists?  Does
W2K return 0xb7 even if the file does not exist?

GDB uses termios, which redirects all screen writes through Int 29h.
So it looks like only DOS I/O is affected.

Tell me about it.  Another report from the trenches seems to indicate
that you cannot redirect stderr separately from stdout.  Could you try
this with `redir' and see if that's really so?

Thanks a lot for your help.
