 Official support for Itanium builds have been dropped from the build. Please
 contact us and provide patches if you are interested in Itanium builds.
 
-The project files support a ReleaseItanium configuration which creates
-Win64/Itanium binaries. For this to work, you need to install the Platform
-SDK, in particular the 64-bit support. This includes an Itanium compiler
