Architectually, the i[3456]86 family are very much alike. Yes, there are
optimisations in the 486, p5, etc.

But pleas e keep in mind that the autoconf is determining for example
what
will became the default optimization target of the compiler. So it's
really a difference if it's i386 or i486! So the broken part here is
really autoconf. And please don't tell me that the 386 and 486 are very
similiar. Think about FPU instructions for example :-)
