OK, so I just learned something about windows 7 today...  Welcome to 
VirtualStore.   When you try to edit a file in Program Files as 
non-admin, Windows silently creates another copy of the file for you to 
edit.

For me it showed up here:
./AppData/Local/VirtualStore/Program Files (x86)/CMake 
2.8/share/cmake-2.8/Modules/Platform/Windows.cmake

CMake for some reason does not pick up this alternate file, and still 
uses the original (unchanged) file in Program Files.  So, the FAQ is 
still good, but you need to edit the file as admin to actually change it.
