I understand why that is important in general, but as a shop which builds from source, and is fine with a separate build for each hardware model / OS version combination, it would be great if any optimizations which are only available if you *do* assume that the build machine and the run machine are the same (or at lease identical) could be enabled with some configure switch. Maybe something like --enable-platform-specific-optimizations. I don't know if any such possible optimizations currently exist, I'm just saying that if any are identified, it would be nice to have the option of using them. -Kevin
