Ok, these are the standard permissions on a stock XP install.

This is weird.  Opening the directory works fine, but when it tries
to read the directory it gets a strange "no such file" error message.
This does not happen on my stock XP test system.  I can enumerate the
directory content just fine.

I'm missing a bit more information in our strace output at this point.
So I created a new snapshot which adds debug output here.  Could you
please (temporarily) replace your DLL with the DLL from the latest
developer snapshot from http://cygwin.com/snapshots/ , rerun 
`strace -o ls.trace ls /cygdrive/c' and send the new strace output?

If I might venture a guess.  This is not a generic permission problem or
some sort of obvious bug in Cygwin, otherwise it should be reproducible
on my machine.  So the usual question applies here:  Are you running some
firewall-, anti-virus-, or Logitech web cam software?  See the mailing
list archives for how certain products interact badly with Cygwin.
