Gopher, I think what Microsoft is going to do is to deliver the code they converted to 64bit, and the rest as a 32 bit executable. Then, you have a feature complete product, that just happens to suck performance-wise. Joe

Gopher, Unfortunately the compiler cannot automatically correct errors such as casting a pointer down to a 32 bit quantity. Why not, the physical and logical number of bits in a pointer is not hardware dependant in modern operating systems. Besides in your example a pointer is a value which I assume can be represented in 32 bits, therefore it can obviously be made to live in 64 bits. It's going the other way that requires magic. Left fill with zero's, ouch! The demos of WIN2K on IA-64 where full up feature rich versions. Stop worrying about the part that will work, i.e. compilers and OSes - start watching the applications side. Why buy a 64 bit machine to run a 64 bit OS unless your favorite "Back Office" application isn't available?
