The following is totally a guess.  You try it at your own risk.

It is possible that the solution is in windows, not cygwin.

Windows can have security settings that propagate down a directory tree.
And when Windows and Cygwin argue, Windows wins.

- Go into Windows Explorer for C:\some or C:\some\path.
        (I advise NOT trying this on C:\.  If you do and it results
           in disaster, it is on your head.)
- Right click and select "Properties".
- Go to the "Security" tab.
- "Advanced".
- Select the account under which you use cygwin.
- "Change permissions".
- You might need to experiment on whether to check or uncheck "Include
    inheritable permissions from this object's parent".
- Check "Replace all child permissions with inheritable permissions
    from this object".
- Select the account under which you use cygwin.
- "Edit".
- "Full control".
- "OK", etc.

Or something like that.

Again, you play with the Security tab at your own risk.

Good luck,
