Of course, silly of me..

And if you use the d:/ syntax, will that translate to the cygdrive syntax 
or to the d:\\ syntax?

>From what I understand of your previous mail, if d:\\ forces textmode, but 
d:/ does not, d:/ is translated to /cygdrive/d whereas d:\\ is not.. Is 
this documented somewhere? (If not, I'll be happy to do the writing).
