Update of /cvsroot/CMake/CMake/Modules/Platform
In directory public:/mounts/ram/cvs-serv18497/Modules/Platform

Modified Files:
	WindowsPaths.cmake 
Log Message:
ENH: Use 32-bit and 64-bit Program Files folders

On 64-bit Windows there may be two Program Files folders, one for 32-bit
binaries and one for 64-bit binaries.  When we compute
CMAKE_SYSTEM_PREFIX_PATH we should put both folders in the path.
