Tench, come on. IA-64 is a new microarchitecture with new instructions. x86-64 is almost 100% compatible with IA-32. I know that in the days of 16-bit code we did not have to do much to get our apps to compile in 32-bits other than change some macros and typedefs. I don't see why it would have to be any different for x86-64.

Hardly, "portable" x86 code is littered with architecture specific code, such as segment specifiers. x86-64 compilers should have little problem dealing with these architecture specific code lines, but I doubt if the same can be said of IA64 compilers.
