That's not quite how it works, Ronald. You were right in tracing back to
/cygdrive, but you should have realized that /cygdrive is a mount in
itself, and it will not get further reduced to "/". So, if you use the
/cygdrive/d syntax, it will use the mode on the /cygdrive mount. If you
use the d:\\ syntax, the files will be opened using raw Win32 calls, and
who knows what the mode will be (ISTR that it defaults to text).
