title: Should my C++ program support IA64 or only x64?
body: <p>Should my program support IA64, or should it only support x64?</p>
  
  <p>I haven't been able to easily find IA64 computers myself.  Is IA64 dead?</p>
  
  <p>MS seems to have a wide support for IA64, but it took me a long time to be able to find an IA64, and I had to end up getting it on eBay.</p>
