Installer cannot write to Cygwin's /usr/local/etc

[Gerry Reno]

I have a Windows MSI installer that first loads Cygwin and then has a deferred copy of some files into /usr/local/bin
and /usr/local/etc.

The copies into /usr/local/bin succeed fine. 

The copies into /usr/local/etc always get Access denied.

I've tried swapping them and same behavior.  The files that would copy into /usr/local/bin now would not copy into
/usr/local/etc.

I'm seeing this behavior on Windows 7 and Windows 2008R2 w/UAC.

The installer prompts the user for elevated privileges to deal with UAC.

Is there some underlying difference in the way that /usr/local/bin and /usr/local/etc are configured in Cygwin?
