[CMake] Problem with "configured" file under Cygwin/Windows 7

[Arjen Markus]

Hello,

I have installed a very recent version of Cygwin on 
Windows 7
(64 bits) and the version of CMake that comes with it 
(2.8.9-2). When I use this however to configure and build 
projects that work fine
under Windows (various versions0, then I get either 
configuration
problems or build problems that turn out to be caused by a 
strange
permission set on "configured" files.

Using one of these projects I have created an almost 
minimal project
to demonstrate the problem. If you configure it via CMake 
under
Windows 7, the file "gnulliver.h" has "special 
permissions". I have
no clue what that means or how it arises, but the 
consequence is that
a program can not open it. Not even a program running 
under
Administrator rights.

Oddly enough, you can change the permissions from Windows 
Explorer by
opening the permissions dialogue and giving the user full 
access.

I have tried to reproduce it in an even smaller project 
than the one
attached, that is: just a CMakeListst.txt file and 
gnulliver.h.in,
but that worked without this problem. So it seems a 
combination of
steps is required to trigger this issue.

Can anyone shed some light on this? It makes it impossible 
to use
Cygwin in combination with Windows 7 (I have not tried on 
other
platforms, quite possibly it is specific to this 
combination.)

Regards,

Arjen
