Indeed.  Unless Intel's CPU design group has been -really- busy... :)

I noticed this problem under b17 as well, and reported it, but I suspect
it got lost in all the rush.  My solution for the moment was to write my
own 'arch' (for autoconf) and ignore the uname problem since it didn't
-break- anything.

Perhaps a way to set this if you have a specific need, and default to i486
or something otherwise?  Unless you have a way to determine the chipset
accurately. :)  Only reason I suggest a way to set it is if you have
something which depends on 386, 486, or 586 compiler optimizations...
