How about:
intel == i386 amd64 == x86_64 (and just forget about ia64 == itanium)
Sounds good to me. Since Intel imposed its name on the x86 processor family, it sounds only fair that we choose AMD for the subclass of 64-bit processors :-) By the way, I wonder how Intel, the company, feels about all this; I read somewhere that Xerox was unhappy about its name being used as a synonym for photocopy (and it's indeed amazing how the widespread the word has become, I even saw it in Kazakhstan. Of course, there it's spelled ксерокс).
and then:
freebsd freebsd-intel linux-64 linux-amd64 linux-ppc linux-ppc linux linux-intel (or just linux?) mswin mswin osx-intel osx-intel osx-ppc osx-ppc osx-universal osx-universal sun solaris-sparc (this *is* sparc, yes?) - solaris-intel
Looks great, but I don't know if the change can be made today without breaking everything. And yes, the "other" processor for Solaris is Sparc. Ultra-Sparc, to be more precise, a 64-bit family of processors. Arthur
