Thanks for the replies, cygwin people!

Sorry, I was not clear -- I mean the same filesystem between cygwin and Windows.  And I only care about the C drive (I've learned to keep everything there).

Well, it's worked pretty well for me for the last 10 years. :-)
Of course I've also learned not to update my cygwin. :-)

Can you say more about this?

Correct -- I don't care about that (D drive etc.).  What I do care about is being able to mix cygwin command line tools with non-cygwin.  For example, Intel compiler.  Or (non-cygwin) python.  I'm really used to being able to say

  # ls /my/path/
  # python !$
  # vim /my/path/   (cygwin)
  # icl -c !$             (non-cygwin)

and have it just work, like on Linux.  Not have to translate paths around and remember which utility is cygwin-based and which isn't. (I'm old, and seem to have become a serious command-line Windows hacker, but I'm still really a Unix guy.)

The above is the big problem for me.  But I guess I'm learning that cygwin 1.7 can't do what I want, at least how I used to do it.

You are quite easy to understand, actually!

This is almost nice, but that annoying /c/ is just as bad as anything else.  If I can't cut and paste paths around, or use my shell history, I will go crazy. :-/

I now think I have to experiment with installing cygwin in the root of the C drive, despite all the warnings to the contrary.  I can be pretty careful about those special root folders (etc, usr, bin, and so on).
