Microsfot would have you believe that a 64bit edition is as simple to make as just starting a diffrent compiler envrionment. this obviously isnt the case all of the time, but if your useing microsfot compilers, code is saposedly easily optimized for multiple platforms, indluding PocketPC, x86, x86_64, IA64, and generaly anything that is a relitivelyrecent release of windows... again..this is a propiganda based post.
