That's okay. What you gave is a good start. I have a couple questions though:
1. How can I distinguish the three processors you described (HP/RISC 32-bit, HP/RISC 64-bit, HP/ITANIUM 64-bit)? I suspect uname might be the culprit. If so, can you provide uname output for the three processors?
2. Is there no way to actually create a truly processor-independent executable (perhaps by creating a "fat" binary)?
Thx,
Skip

Would not it be better if you let the users (people who compile Python) decide what they want? There are several reasons for this: 1) It is hard (== unreliable) to try to distinguish them using 'model', etc.; 2) Reliance on such techniques will inevitably break overtime when the new processor denominations come into play; 3) Most importantly, it is possible to be on the 64-bit machine and be purposefully compiling for a 32-bit processor (to cover the broadest customer base). It is also possible to be on RISC and compile for ITANIUM and vice versa, because it is the same compiler. Moreover, ITANIUM machines will run RISC binaries. In other words, the confusion never stops ... People, on the other hand, usually know what machine they are working on now, and what machine they want Python to work on after they built it. There will be less surprises for them of the sort "Oh, that what happened during the compilation!... I had not idea ..." after the fact that you built this, distributed it to somebody, and had report back that it all failed. Maybe there should also be some sort of option for expects who will not want Python to be compiled for generic processor; who might purposefully want to compile Python on their particular hardware and have it fully optimized for it to gain maximum performance.
