Looks like. Be sure I'm doing my best to understand, anyway.

That's a point I don't understand. What sense can mount have without
bash's unix-like environement ? Ok, it's not bash alone. It's everything
around also. But I see a big difference between running from bash with
everything around, which looks like unix, and running the compiled
application from Windows' Dos Box. The only common thing I see is
cygwin1.dll.

Regarding what you said before, I guess I'm wrong. Anyway, say I'll run
mount from my friend's Dos Command Box, who has no cygnus system
installes, what command am I supposed to type ? I don't see *where* I am
supposed to mount the drives. Do you mean thet mount also can set the
drives "mode" (text vs binary) without really mounting them ?

That may explain why I could not see the flag on linux's man pages. But
there is no man page for open(2) on Cygwin, right ? Then, where am I
supposed to find the value for this flag, if it ever exist ? I can't just
invent it, I guess it won't work ;)

Maybe I could save your time. I feel a bit guilty... Is there a kind of
reference manual for Cygwin that explain all this ? It doesn't sound that
evident to me.
