Well,

It seems we're partially the way there, but mintlib doesn't respect
UNIXMODE's settings at libc startup.

Here's a patch (delete the other one - so don't use it), and use this.

Now we default to binary if UNIXMODE specifies it for stdin, stdout and
stderr. If UNIXMODE doesn't specify 'b', then it's only when isatty(x)
is true that we're in binary mode & under FreeMiNT - see further down
the file for this. Should these change too ??

Alan.
