Could you please explain what the problem is you're complaining about instead of assuming everyone knows the details by heart? The only reference I saw to 'i386' in PEP 345 is in the section about Environment markers and that only refers to the CPU architecture in a test for CPU architecture (platform.machine == 'i386') which seems reasonable to me.  

You can use "sys.platform" to detect various OS types.

BTW. I guess you mean "Windows" where you write "pc".

'i386' is the commonly used abbreviation for an instruction set also known as 'x86' or 'ia32' and doesn't suggest any particular OS to me, all of Windows, Linux and MacOSX use or can use 'i386' capable CPUs (to just name 3 commonly used operating systems).
